Friend, has housecats and they done go out. He adores them. But...
Two females ages 2 to 3 form kittens, never vet registered and not netured or wormed or fleaded regularly.
Live in living room only which isn't that big, no scratch posts, beds or toys realy and place is very messy.
Fed 2 pouches between them a day and busicuits... If he can afford it often no biscuits end of month. Litter tray is frankly grim.. Can smell it and viably full of poo very often.
Is this neglect? I think it's borderline but he clearly cares about them. They got poorly and I pointed out needed worming and fleaing then got better.
