My sweetest boy is the light of my life. I adopted him when I fostered his mom and siblings, I literally met him the day he was born and he chose me right away, even though I didn't want to foster fail. 
He's glued to me all the time, he's always cuddling with me and he's been with me for the past eleven years through the best and worst times of my life. I love him so much. 
I knew he started having arthritis a last year as he was showing signs: I was very proactive about it, and started him on a supplement program to delay it as much as possible. He's quite stiff, he doesn't jump anymore and has a limp on his front right leg. Today we went to the vet for x-rays to see the progression of his OA, as I couldn't financially do it earlier. It's bad. One hip joint is completely destroyed and is bone on bone. The rest is pretty bad too. I didn't expect such a bad news. I'm devastated. 
We tried Solensia last year when arthritis wasn't that bad, and while it worked for his mobility, it wrecked his points and gave him a bad reaction on the third injection, so we stopped. 
We're now trying Cartrophen, but without much hope. 
I feel so helpless. He has stairs and is comfortable, still eats/drinks /pees/poops well, but I have a hard time accepting the fact that he will leave me sooner than I thought. 
Does anyone has stories about their OA kitty that would give me hope? Should I expect him to leave us in six months? More? 
I can't imagine my life without him and have been crying the entire day... 

My 11 years old kitty has bad arthritis....he's my everything
