FOOD – We suggest the use of high quality cat foods such as Iams or Science Feline diets, because these are made up of highly digestible top quality meat proteins. For the young ferret under three years of age, we recommend the growth or kitten formulation of these diets because of the higher fat content. For the ferrets that are over 3 years of age we recommend using the maintenance or adult cat formula. There are also a variety of pelleted ferret diets available on the market which are also suitable. Some people like to mix a cat food and a ferret food together which is also acceptable. When checking the food label, make sure that the protein level is between 32% and 38%. A protein content over 40% may be detrimental to the kidneys of the older ferret.
Another item to check in the food is the ash content, because ferrets are prone to develop bladder stones on the foods that are high in ash. The foods recommended above are all relatively low in ash.
WATER – Clean, fresh water should always be available and can be given in either a water bottle or a heavy ceramic or weighted bowl. Ferrets like to play in their water and overturn it, so keep that in mind when selecting a container. Supplements do not need to be added to the water.
VITAMINS – These are not necessary in the healthy pet. Your veterinarian will prescribe any that may be necessary in the case of disease.
TABLE FOODS – Cooked meat and egg scrapes are suitable table foods to offer your pet as a treat. Do not feed anything that contains bones. Many ferrets also adore a bit of fruit or vegetable, but these items should be fed sparingly, because ferrets cannot digest fiber very well. If too much fruit or vegetable matter is given, it could lead to diarrhea. The rule of thumb is no more than a total of one teaspoon per day of any treat should be given. Some favorite fruit and veggie treats are cucumber, green pepper, banana, raisin, and melon.
NEVER FEED YOUR PET FOODS THAT ARE HIGH IN COMPLEX CARBOHYDRATES OR REFINED SUGARS
Ferrets cannot digest a lot of sugar and feeding these types of foods puts a tremendous strain on the pancreas. The result is diabetes. This disease is extremely difficult to treat in the ferret and ultimately leads to an early death. So, do not feed candies, cakes, sugar coated cereals, ice cream, etc.
FATTY ACID SUPPLEMENTS – As already mentioned, ferrets have a high fat requirement and it may be necessary for some animals to receive an additional supplement to improve coat quality. We find this most essential during the winter months, when the air in our homes is very dry and detrimental to the ferrets skin and coat. We recommend using any fatty acid supplement as used in cats (such as Linotone) and feeding four to five drops daily on the food. Many ferrets really love the taste and will take it right off a spoon.
HAIRBALL LAXATIVE – The accumulation of hair in the stomach of the ferret is a very common occurrence (especially in the older animal) and may result in a costly surgery to remove it. It is much easier to prevent with the use of a hairball laxative. This product generally comes as a sticky past and ferrets love the taste of it. We recommend giving a ribbon one to two inches in length every other day. This medication acts only as a lubricant and does not cause any diarrhea. If you pet has never tasted this before, it is sometimes necessary to smear a little on their lips to introduce them to the taste.
CAGE – The basic cage needed to house up to two ferrets is a wire rabbit cage (24″x24″x18″ high) with a wire or solid floor. Newspaper or pine shavings may be used under the wire floor. Aquariums are NOT suitable cages for ferrets because the ventilation is very poor. All types of elaborate caging arrangements may be built by the creative owner. The use of a section of PVC pipe or large cardboard mailing tube can provide a good place for the ferrets to exercise and play in. IT IS HIGHLY RECOMMENDED THAT YOUR PET BE CAGED WHEN YOU ARE NOT HOME to prevent any tragic accidents.
SLEEPING AREA – An enclosed sleeping area is NECESSARY or your pet will become extremely frustrated and continually dig at the corner of the cage. A sleeping area can be as simple as a towel or shirt, and old stocking cap, a cardboard or wooden box with a hole cut in the side, the sleeve of a sweatshirt, etc.
LITTER BOX – Ferrets can be litter box trained about 90% of the time. A small low-sided box should be placed in the preferred toilet area of the cage (i.e. let your pet pick the spot first, then place the box in that area). You can use kitty litter (avoid the perfumed types), pine shavings or cellulose bedding in the box. Ferrets do not cover up their waste; therefore, it will probably be necessary to change the box frequently to minimize the odor. When your pet is loose in the house, it maybe necessary to place several litter boxes or paper in various corners, because ferrets are not very good at returning to “home base” if they get the bathroom urge and they are far away.
TOYS – NEVER GIVE YOUR PET ANY RUBBER TOYS! Ferrets like to chew and swallow rubber which could result in an intestinal obstruction and death. Make sure to FERRET PROOF your home and remove access to any rubber items such as ear phones, stereo speakers, rubber soled shoes, pipe insulation, molding, etc. (While you are at it make sure to get down on your hands and knees and check for any escape holes that the ferret could get into, and plug them up) Safe toys to give your pet are nylon bones, ping pong and golf balls, small cans, paper bags, cardboard mailing tubes, and very hard plastic toys. Most cloth toys are also suitable, but check carefully for the first week to make sure your pet in not chewing off pieces of it.
CANINE DISTEMPER – THIS DISEASE IS 100% FATAL IN THE FERRET! Please have you pet vaccinated to prevent distemper. Even if the pet never leaves the house, it is possible to bring the virus home on your shoes or your clothing. Youngsters should receive their last booster by 12 weeks of age. Thereafter, boosters should be given annually.
RABIES – There is now an approved rabies vaccine for ferrets. We recommend the vaccine for all ferrets that will be in any high risk situation where a potential bite may occur. The first vaccine should be given at three months of age with annual boosters thereafter.
IV. MEDICAL PROBLEMS
STRONG BODY ODOR – The ferret produces oily secretions on the skin that have a very strong odor in the mature intact male and female. The odor is under the control of sex hormones, so therefore, when your pet is neutered the odor is largely eliminated. There is also an odor associated with the anal glands (or scent glands) of the ferret, but this will not be noticed unless your ferret sprays the material, usually in response to a fearful situation or when extremely excited. Most ferrets do not express their scent glands with any frequency, and if they do, the odor only last a few minutes. Therefore, it is unnecessary to remove the scent gland of the ferret unless there is disease present.
Bathing should be done with a gentle shampoo. Ferrets do not need frequent baths and every two weeks is the absolute maximum. Bathing tends to strip the skin of its essential oils and can lead to a dry itchy condition if done too often.
FATAL ANEMIA OF FEMALES – When the female ferret goes into her heat cycle, she will remain in that cycle until she is bred by a male. During this heat period, the levels of the female hormone, estrogen, are very high and it can have a very damaging effect on the bone marrow. The hormone causes the bone marrow to gradually stop producing white blood cells and red blood cells. The condition comes on so gradually, that by the time the external signs of anemia are seen, the condition in the bone marrow is irreversible and the ferret dies despite therapy.
The condition is totally preventable by having your pet spayed. The operation should be performed by the time the pet is six months of age. If your pet comes into heat prior to that time, she can be safely operated on even while she is in heat.
If you wish to breed your pet, but do not wish to do it during a particular heat cycle, then a hormone injection can be given to take her out of heat temporarily. However, these injections should not be used instead of the spay if you have no intention of breeding your pet.
FLEAS – Ferrets get fleas just like other mammals. If your pet has them, please us a flea product that is safe for cats, such as a powder or a pump spray. Do not use flea collars on ferrets. Remember to also treat the house and yard, as fleas spend most of their life off of your pet laying eggs all over the environment.
HEARTWORM – Ferrets are susceptible to heartworm disease. This is a microscopic parasite that lives in the salivary glands of the mosquito and is transmitted to the pet through a mosquito bite. The larva then grows into a large worm that lodges in the animal’s heart and can cause disruption of the blood flow and death.
We recommend the use of a heartworm preventative, called Ivermectin, which is given once a month from April to October. There have been no side effects to this drug. A heartworm test is not necessary, but a recent physical exam is recommended prior to starting back on the medication each year.
COLDS AND FLU – Ferrets are highly susceptible to human colds and flu. They will develop the same symptoms as humans do. They will have runny noses, watery eyes, and may develop sneezing or coughing fits and be off food for several days. There is generally no need for any medications, just tender loving care and lots of rest for five to seven days. If, however, your pet completely loses its appetite, develops green or yellow eye or nasal discharge, or becomes depressed or lethargic, please call your veterinarian right away. Some viral flu infections may require more supportive care or a secondary bacterial infection may require antibiotics.
FOREIGN BODIES IN THE STOMACH OR INTESTINE – As mentioned previously, ferrets are very prone to eating rubber, and they are also prone to developing hair balls. Other items that ferrets have been known to eat include soft plastic items, cotton balls, bones, and towels. The symptoms of a foreign body that has found its way into the digestive tract are varied depending on where the material has lodged. Some of the symptoms that might be noted are gradual wasting, extreme depression or lethargy, vomiting, persistent dark tarry stools and loss of appetite. If any of these symptoms are present in your pet, do not wait and have him examined as soon as possible by your veterinarian. EXTREME LETHARGY OR DEPRESSION IS AN EMERGENCY!
GERIATRIC DISEASES – Unfortunately the average life span of the ferret is five to seven years. Starting at about three years of age we see a marked increase in a variety of diseases in the ferret. Cancer is very common, along with liver and kidney disease.
