Best Answer: I would say no. I have had 5 rabbits. My buck is fathering 12 babies at the moment. I have never given my rabbits vitamins in their water. My first rabbit lived to be 9 years old.
It is possible to overdose a rabbit on vitamins.A lot of pet stores will try to sell you vitamins to put in their water. They just want your money. (Some are on the more expensive side) As long as you are feeding them a proper diet and ensuring they have plenty of fresh water at their disposal,pellets of rabbit food and hay they shouldn't need extra vitamins. Timothy hay is best for rabbits over a year old and Alf alpha hay is best for rabbits less than a year old. It provides extra nutrients that pellets alone don't provide. With a balanced diet, your rabbit will be fine without adding vitamins. Make sure you don't feed them too much of one kind of particular veggies or fruits as this can cause wet tail. Hope this helps.
I wouldn't recommend putting anything in their water. Often, animals that taste strange material in their water will simply stop drinking it. Just keep up a steady diet of mostly hay and fresh veggies and some pellets. See my source for some good info on rabbit nutrition, and if you have any more questions, you can always call your vet and ask. ;)
Your relatives are wrong.. Rabbit care and info.. Here are the most important items that you should be sure to include in your rabbit's diet. WATER The importance of adequate water intake cannot be overstated. A rabbit who does not drink sufficient water will gradually begin to suffer desiccation of the intestinal contents. Skin tenting, a common method used by veterinarians to gauge the state of hydration in many animals, is not a good gauge of hydration in rabbits. It seems that even when the tissues of the rabbit appear to be well-hydrated, the intestinal contents may not be, perhaps because the rabbit is so efficient at sequestering necessary fluids from its own intestine. When this happens, the ingested food in the stomach and intestine becomes dry and difficult for the normal muscular motions to push through. This can start a downhill cascade into a condition known as ileus, which can be life-threatening if not recognized and treated. HAY! Perhaps the single most important item in the rabbit diet is grass HAY, and it should be fed in unlimited quantities to both adults and baby rabbits. A rabbit fed only commercial rabbit pellets does not get enough long fiber to keep the intestines in good working order. The long fibers in the hay push things through the gut and keep the intestinal muscles in good tone. In addition to keeping the intestinal contents moving at the rate at which nature intended, hay may also help prevent intestinal impactions caused by ingested hair or other indigestible items. (For more information on problems associated with slowed intestinal function. PELLETS A high quality commercial rabbit pellet provides trace nutrients, vitamins and minerals that a rabbit might not get if fed only hay and fresh foods. However, very little pelleted food is required for good health. Many experienced rabbit veterinarians are now recommending no more than 1/8 cup of quality pellets per 5 lbs. of rabbit per day, and some even consider commercial pellets a "treat food" that can promote obesity in spayed/neutered adult rabbits. A rabbit fed too many pellets will sometimes ignore hay, to the detriment of the intestinal system. A good quality rabbit pellet DOES NOT contain dried fruit, seeds, nuts, colored crunchy things. FRESH VEGETABLES Fresh, moist greens are about as important as hay in maintaining a healthy intestine. FRESH FRUIT? These are considered treats, and should be fed in very limited quantities (no more than two tablespoons a day for a five pound rabbit!), if at all. Safe choices are apple, apricot, banana, cherries, mango, peach, plum, papaya, pineapple, apricot, berries....just about any fruit you would like is okay for your bunny. Be very careful not to overdo these treat foods, as they may promote cecal dysbiosis, other intestinal problems and create a desire in the bunny to eat treats instead of his/her normal, healthy foods.. Remember: a rabbit is a lagomorph, not a rodent or a primate. The rabbit digestive tract is physiologically more similar to that of a horse than to that of a rodent or primate, and the intestine and related organs can suffer from an overindulgence in starchy, fatty foods. Select at least three kinds of vegetables daily. A variety is necessary in order to obtain the necessary nutrients, with one each day that contains Vitamin A, indicated by an *. Add one vegetable to the diet at a time. Eliminate if it causes soft stools or diarrhea.. Alfalfa, radish & clover sprouts Baby bok choy Basil Beet greens (tops)* Bok choy Broccoli (mostly leaves/stems)* Brussels sprouts Carrot & carrot tops* Celery Chinese celery Cilantro Clover Collard greens* Dandelion greens and flowers (no pesticides)* Dwarf choy sum Endive* Escarole Gai long Green peppers Kale (!)* Mint Mustard greens* Parsley* Pea pods (the flat edible kind: snow pea or sugar snap pea)* Peppermint leaves Raddichio Radish tops Raspberry leaves Romaine lettuce (no iceberg or light colored leaf)* That's why pet shops should not sell animals, they give out wrong info that can kill the animal.. If your family dose not provide water for that Rabbit he WILL DIE and that is called animal cruelty.
