This is all wonderful information! I cant thank you enough for your help! I plan on asking my vet tomarrow about Elavil and Cosequin for Oliver. He is a little better today it seems...not so irritable with everyone...but I'm thinking it's because he finally ate something. He's refusing to eat the c/d food and was literally starving to death and losing weight by the hour, his bones actually make it hard to hold him. I mixed a little Iams urinary tract soft food with the c/d and he gobbled it right down. I hope this didnt hurt him, but I figured if he didnt eat something soon he wouldnt make it much longer. I've given him the mixture several times today and he's eaten most of it and his need to squat and urinate every minute has slowed to about every 5 minutes with a larger amount of urine output...he can be soooo stuborn and being ill on top of it has made it worse.
Thank you again for all your help, I'll keep you posted on his situation
