How long will a cat's foot be sprained?

Answer

Pet foot sprains are much the same as humans. I am hoping you took your cat to the vets to be sure the foot isn't a hairline fracture or a full broken bone. If not get to your vets. If you have been to the vets the vet would have told you when to bring the cat back in to be examined and to see how the foot is healing or, the cat may start walking on it's own.
