I am new(ish) to cats . We got our 2 young adults from CPL last year.
Yes there is a vetting process for owners-to-be
Online form (I think there was a section about why I wanted these cats ), my experience with cats , did we have outdoor space .
Many years ago I had a Rescue cat (lived to be 17yo)
They Google Map the address to check roads .
Phone calls from CPL
Went to meet the cats
Home Check
Settled the cats
Donation fee
So yes , it is thorough .
I have adult DC , no dogs, big garden. Got them a catdoor .
So these two (they had no previous owners except Rescue) had their challenges . And they do treat the place like a hotel.
The female is a bit mouthy ( not a bite but a skin grab) the male is a bit shy still.
But they know they're home , we love the little furry reprobates .
Similar to you, I've kept small pets , DD and I had 8 rescue guinea-pigs over 8 years . Our soppiest boar was taken on holiday boarding and not collected . Seemingly it is common. At least he wasn't dumped in a park, or given away (I think there's a dog bait issue with small furries too)
Our cats were in a home environment . I think the rows of perspex pens is a sad depressing sight , but at least they are fed,cleaned and cared for .
