You're quite right there, if I hadn't seen those 2 when I did, I would probably just have gone to Lesley as she's so close! I feel very attached to them now so I am carrying on with this for their benefit as much as mine.
Ela, I can't see why the neighbours not liking cats should be a problem, the residences are seperate, each with our own front door going straight outside, surely its no different to people in houses living next to each other and one having cats.
And yes, its very annoying that the shelter would probably turn me away if I mentioned keeping them as indoor cats, its certainly safer for the cats that way!
