Cats Protection won't let you adopt one of their cats as an indoor cat. Not sure if that's the norm or just them.
No need to hate on pedigree cats. There is certainly a place for pedigrees, and a place for people who do their research and are attracted to the traits of a specific breed.
However breed is not a cast-iron guarantee of personality. Cats are individuals.
Cat's Protection are particularly bad.
They turned down my Grandmother to adopt a cat because they thought she lived on too busy a road. I've heard similar stories from others.
She had multiple cats there for years already and more after, never lost one to the road. They all died of old age and they were allowed out (the back of the house).
They approved me and my wife because our road looked quiet... and one of ours was run over
Go somewhere else... I have a distinct disdain for the CPL... they would rather kill a cat than give it to a good home they deem to be unsuitable...
There are many unwanted cats and kittens in shelters... too many get euthanised... I'd always advocate re-homing one of those guys. They'll appreciate it.
The most loving kitty I've ever come across was one we found at 4 weeks old playing in the middle of the road in the middle of nowhere... no house, no parent cat anywhere nearby. We took her in and you wouldn't believe the affection a cat can give... I didn't.
Please rescue... the bred cats won't go without a home or life.
The rules on keeping an indoor cat are... if they've always been an indoors cat... then that's ok because they haven't known different... if they've been outdoor cats, then you shouldn't keep them in (in fact, I think that's illegal in UK... amoung other countries).
For indoor, just make sure you tailor your home to them... Jackson Galaxy from "My Cat From Hell" TV show has shown some cool stuff. Check him out if you haven't already. I've learnt a lot from him and even this evening I was using the things I'd learnt from him in regards to cat body language to make friends with a wild cat who has started showing up at our new back door the last few nights.
