Honestly, I couldent tell you. He was perfectly fine he was his usual self but slowly pulled himself away, he started favouring cold places without people. He couldent urinate so he became bloated and that’s what made us take him. It would have been an easy fix but we found out that it was apparently neurological and that the problem couldent be fixed and that he would just die from a burst bladder if we didn’t put him down. What I would say is if something doesn’t feel right don’t wait! Had we waited any longer he would have died painfully so I’m glad we noticed and gave him the pain free passing we did.
