My mum has dementia and went onto a care home 6 months ago. After being unable to rehome her cat, I had to take it on myself. The cat is on life-long medication and the vet is now recommending special food too, all of which costs money. I have Power of Attorney and Mum's house has just been sold, so she is paying her own care home fees until her savings reach the level at which the council will take over payment, which will be several years' time. Is it reasonable to expect Mum to pay for her cat's upkeep or at least contribute towards it? It was not my choice to acquire an expensive cat, but the only other options were to put it permanently into a cattery or to have it put down. At least this way Mum gets to still visit her cat.
