We have never had a bought pet, always rescues, both dogs and cats. When you welcome an adopted pet into your home, their individual characteristics and uniqueness are quite clear, and the names just come naturally.
Minou our current cat, was found severely injured and totally wild. Took me months to tame him and be able to take him to the vet, and we always thought he would have to be pts, as he was in so much pain. So we called him Minou- the equivalent of 'puss' in English- as we never expected him to live and be our beloved pet cat. That was 8 years ago and he is now about 9 or 10. And Minou he will always be.
Our previous 2 cats were 'Pudding' as she was a large grey and white cat with a big hanging belly - we had her 23 years, so she was at least 25 or more when she died, having made the big move with us. She was found by the M1/M69 jct- with many kittens and another small female in sealed cardboard box! b****rds! Kittens fed willy nilly from either mum when in foster home. Little black one was so so soft, never felt such a soft cat- so Silky she became obviously.
