Yeah that was my situation he wasn't going to get any better.I have only had one animal that I hated to have her put down. She was sick and wasn't going to get any better. When I went to the drive in window at the bank, they would always sent out a treat for her. She would always get excided when we pulled up to the bank. She knew she was getting a treat.
Same with my other cat who had a huge cancer tumor on her mammary area. Apparently that's a thing in cats. That one she always hated me so I didn't know she had a tumor until by chance I saw her flop over where I could see it. I still cried a little putting her down but we were never close like my buddy Boots.
