My oldest cat Pita (almost 13) is arthritic in her hips, its gotten a little worse recently with the cold weather we have had here in S. California. My vet did her blood work and x-rays and she did determine shes arthritic (hellllooo? I told you that before the $400 tests!). She called me today and said she should have anti inflam shots once a month (no problem) and to give her one baby aspirin a day, which is also anti inflam and will help with her joint pain. I have never heard of that. Has anyone else given baby aspirin to their cat? She also told me her enzyme levels were elevated in her kidneys, so thats a new problem a little more down the road. I just dont want her in pain. She sleeps on a heating pad at night and big thick warm blankets on the couch any other time. Does anyone else have any suggestions?
