We have two old cats, Missy and Petey who are around 15. Missy's hips are wearing out and Petey has arthritis real bad. We have them on buprenorphine. It is expensive but gives relief. They get it 3 times a day. The vet wants to wean them off of it but the cat's are hurting. I think the vet is giving up. We also give them laser treatments. I realize that the time is near to send them across the "rainbow bridge" but other than the aforementioned problems they are OK. Is there anything else not as expensive? Is there a cheaper source for the buprenorphine? Any ideas to make their remaining days comfortable? Thanks.
