My cat came home after missing, with a weak, sunken back leg.

I'm glad Panda returned home! Limping is a sign of pain in cats, and if she can't jump onto the sofa, then I suspect she may have an injury to her spine, hips, or back legs. Muscle wastage and weakness in her back legs is serious as well. I would take her into a vet immediately. The vet can do a physical exam, blood tests, a urinalysis, and a lameness exam to determine what is causing her symptoms, and how to treat them. She could have gotten hit by a car while missing, or attacked by another animal. Please take her into the vet now.

Limping means Biscuit is in pain, and I would consider that a sign of distress. She's also showing you she's in distress because she won't eat, that tells me she is in a lot of pain. I would take her into a vet now to get checked out.

Oh my. This is quite concerning. Bunty could have sustained a musculoskeletal injury to his hips (dislocation) or he could have a saddle thrombus (blood clot in lower limb). He needs to be seen by a vet right away for testing and medical care. I hope your kitty turns out ok. Best wishes and take care.

Hi. Poor buster. If all those tests were normal, I would recommend radiographs to look at the bones, also consider a referral to neurologist. If it isn't orthopedic, it could be neurological in which the nerves that control the movement and signals aren't working appropriately. I would discuss this with your veterinarian.

I am sorry This happened to kasey. I would recommend taking him to a veterinarian immediately. I am not sure what caused this but now kasey needs immediate care. Kasey is most likely dehydrated and if he is not eating he could get fatty liver disease which is very difficult to treat. The feces could be soft/ diarrhea secondary to stress , toxins or something he got into when he was lost. I hope kasey feels better soon

If your cat cannot move his back legs, this is an emergency that needs immediate veterinary attention. Its possible that he may have thrown a blood clot to that has ruined his ability to have circulation to his back legs. Or he may have had something tramatic happen to his spine. Either way, Jebat needs to be seen by your veterinarian immediately. Hope he feels better!

Hello, and thank you for using Petco Pet Education Center, formerly Petcoach. While it's *possible* that Ernie has a mild injury like a sprain, in all truthfulness a minor sprain wouldn't usually cause a cat to act as lethargic as you described with Ernie. Cats are pretty good at getting around on 3 legs, so usually with a sprain or similar minor injury, they're just as active as ever but simply put less weight on the sore leg. If he's sleeping an unusually large amount, and eating less than usual, that sounds to me like he's feeling ill. My biggest concern in a kitty who spends time outside and is now lethargic and has a sore leg, would be a bite wound, usually from another cat - they can be very sneaky and hard to find until the resulting infection flares up. It would be worth having Ernie seen by your vet if he doesn't seem back to his usual self tomorrow. Hope this helps!
