My cat, Cleo, has just been PTS after 13 happy years with us. She had been going downhill for a week and hadn't eaten and drunk hardly anything. Vet said she was very dehydrated (not surprisingly) and her temperature was only 35. Vet suggested Cleo could be put her on a drip to help rehydrate her but thought she may have kidney problems anyway .
Rather than subject her to a load of uncomfortable treatments I felt it was time for her to go.
They gave her an injection to make her sleepy first and we cuddled her whilst it took effect. She was completely unaware of the final injection.
Her litter and bowls still need to be cleared out but I can't face doing that at the moment.
RIP Cleo
