We went to our vet with our new adopted kitty Lily for a stubborn URI that she has been battling since we adopted her (previously she was seeing the shelter's vet). As this was her first visit, we gave them all her health history (as much as we could) and had physical exam. Lily is a very small cat at only 6 Lbs. She is 2, and has been spayed. She was a rescue, brought into the shelter pregnant, had her litter and they were all healthy and I was told she was a very good mom. My vet mentioned though that she believes her pregnancy took a toll on her. She says that her weight is OK for her size (fat wise - has a waist, no ribs etc...) but that she has lost (or maybe never had enough to begin with) muscle mass in her spine and a bit in her hind legs. So I was wondering if anyone has had experience with rehab exercises, specifically for the spine. I have done rehab for hind legs before as my other kitty (RIP) had CKD and significant muscle wasting in the legs, but I'm not a familiar with specific exercises that can help strengthen the spine. Any tips would be great.
