To cut a long story short, my dad is getting my grandparents a cat. My grandparents are in their late 70s but he is paralysed and she has severe dementia. They have had a live-in carer for about a year (before that they were not coping at all) and the carer doesn't like cats. The worst part is that the cat is two years old and is therefore highly likely to outlive my grandparents. AIBU to think that this is really unfair on the cat?
