I think the landlord is being reasonable in that they are there at the moment but he doesn't want them there permanently. Personally I just don't get what the problem is but that's me (and probably all of you as well)
I would take them like a shot if this were my house but Mum is a bit weird about stuff, I had to fight to get our two rescue cats, she adores them now, but I really had to grovel to get them in the first place.
There's a thought.......Does anybody want rehome a geriatric woman? Then I could have the geriatric cats.
Thank you for your comments, I am sure something will turn up.
