So a 4 week old kitten that is at the vet is currently getting fluids and medicine. It has nats inside it and they were flushed out and has a swollen right rear leg. The cat eats and is getting all the fluids needed. The only thing is that the cat is not doing is walking. It has all other functions: moving the head around, picking up head to eat, stretching paws, reacting to pinching of paws and moving the tail. Do you have any idea why it would not walk or even put wait on the legs when you try to make it use its legs?

Of it is at the vet, why not ask them.
