MY CAT IS 15 YEARS OLD HIS BUTT IS PROTRUDING, HE IS STILL EATING AND DRINKING. HE HAS HAD A HISTORY OF CRYSTALS AND HE IS WALKING VERY BADLY. I FEEL BAD BUT SHOULD I PUT HIM TO SLEEP HE SEEMS OKAY SORTOF AND I AM BY NO MEANS ABLE TO AFFORD A VET BILL AT THIS TIME DUE TO MY HUSBAND SURGERIES. CAN YOU ADVISE IF THERE IS SOMETHING I CAN USE ON HIM TO HELP THIS OR WHAT
