How to help a cat recover from hip dislocation surgery
Give your cat vet-recommended amounts of food and water.
After the surgery, your cat will probably have very little appetite, and may not want any food for a day or two. Follow your veterinarian's advice on how much to feed your cat following the surgery, and make sure your cat has access to clean water.

Available choices: (i) Providing your cat with too much food and water after surgery will make it nauseous, and it may vomit. Prevent your cat from licking or grooming the stitches. (ii) If your cat is not vomiting as usual after the surgery, you should get her more fluids. Different types of cats prefer different water sources, and so may help her more easily recover from the surgery. (iii) If you cannot keep your cat hydrated after the surgery, your vet may suggest supplementing water with an iv and a stool softener. Be sure to monitor your cat closely as well. (iv) Avoid giving your cat soiled water, when this might be a cause for concern. Ask your vet to recommend alternatives if your cat's had a leg injury in the past.
