I'd heard that too about Cats Protection, but don't know if that's a CP policy, or just one adopted by some over-stretched under-resourced branches (and I can understand why that may happen)
I think shelter to shelter varies, and it depends on the immediate resources and facilities with which they operate.
Some of the rescues in our area use foster homes only.
Others have designated rescue premises but with animals coming out of their ears, and seem unable to turn more away as they just get dumped on their doorsteps - sometimes even by the police who "have nowhere else to try."
I agree, I think the purpose of home checks and responsible pet ownership should be heavily emphasised, but there are many who will continue to adopt pets with no real idea of what they're taking on, or the complex requirements of some of the pets up for re-homing.
Still - it's better to do something than do nothing, and that's what this programme is doing.
Wish the dolly bird wasn't dressed like she's about to trip off to some festival though. It did make me laugh when one of the potential adopters asked her solicitously if she was cold, and she admitted it was "a bit nippy." This is Newcastle luv, this is what passes for our summer - what were you expecting, sat there in your cold shoulder top and silver block heeled boots....?
