What do you if your cat lost its muscle in back legs?

1. Take your cat to the vet. This is the most important step, as your vet will be able to determine the cause of the muscle loss and recommend the best course of treatment.

2. Provide your cat with a comfortable place to rest. Your cat will need to rest in order to heal, so make sure they have a comfortable place to do so. This could be a soft bed in a quiet room, away from other pets and children.

3. Offer your cat plenty of food and water. Your cat will need to eat and drink plenty of fluids in order to recover. Make sure they have access to fresh food and water at all times.

4. Follow your vet's instructions. Your vet will give you specific instructions on how to care for your cat during their recovery. Be sure to follow these instructions carefully in order to ensure the best possible outcome for your cat.

Additional tips:

* If your cat is having difficulty walking or standing, you can support them by placing a towel or blanket under their belly and lifting them up.

* You can also help your cat by gently massaging their back legs. This will help to improve circulation and reduce muscle atrophy.

* Be patient. It may take some time for your cat to recover from muscle loss. Just be patient and supportive, and your cat will eventually make a full recovery.
