We have a neutered boy who is 10 years old. He is a house cat because we live on a busy road, but we do take him out into the back garden under supervision. His adopted sister who was 6 had to be put to sleep at the start of lockdown as she had a very large abdominal tumour. He is an extremely affectionate cat and has become more so since he lost his friend and since 2 members of the household were at home on furlough, he constantly wants to be cuddled by everyone which is fine until people who arent fond of cats come to visit. He is all over everyone, visitors, workmen etc. We would like to get him a new friend for company, but are unsure if we should get a kitten or another older cat who would be happy as a house cat. He can be a bit of a grumpy old man at times. Any advice please?
