Walking
If a cat refuses to walk or has little energy, they may be sick.
Leashes
Cats are not used to being on leashes, so a cat that does not like to walk on a leash is common.
You've had too much to drink...
It is probably nothing serious just give him/her some time. :)
take your mouse to the vet instead of asking the internet!
The Cat Who Walks Through Walls was created in 1985.
He probably sprained it, twisted it, stepped on something sharp, or broke a bone. Take him to the vet.
The ISBN of The Cat Who Walks Through Walls is 0-399-13103-5.
If the vet was unsure of what was wrong with your cat, then maybe the vet gave your cat the wrong kind of medication so it didn't cure your cat. If the veterinarian is unsure of what is wrong with the cat and medicated him anyway, he is obviously incompetant and you need to see a different veterinarian. The wrong type of medication could seriously harm your cat and to prescribe it anyway is irresponsible.
broken belt in a tire probably due to bad allignment
I don't have a cat either.
Nothing is probably wrong, it's just that your cat seems to be very sociable.
No
Grumpy cat has feline dwarfism and an under bite. This is what causes the features that make her look permanently perturbed. It also results in her being very petite, and sometimes a little wobbly when she walks. Overall though, the vet says she is quite healthy.
