Cats and roads just don't mix. Before I left home, we had a cat (ex-stray) who used to lie in the road, and make cars drive around him. Fortunately it was a very quiet 20mph zone, and he was never hurt. But then my mum moved, and the new house was on a busy road. You would think that a former stray would be streetwise, but he lay in the road, and was hit by a car. He lost one leg. Once he was recovered enough to climb the fence, he got back on the road and got killed.
My current cat Spook has a small disability - one of her hind legs is about an inch short, and has a clubfoot. She gets around fine, but she doesn't climb or jump very well. I'm worried that she wouldn't be able to hold her own against dogs or other cats. She's an inside cat, and only goes out in the garden when I'm with her.
I found that I was unable to adopt in my area - apparently there was a shortage of kittens, so you had to go on a waiting list for an HV, and then if you passed, go on another waiting list for a kitten. They wouldn't let you adopt just one, you had to take two, and they didn't home kittens under 6 months old. They told me that I couldn't have one because I'm in a rental property, unless I had a letter from my landlord giving permission, and they could call him to confirm. I didn't even dare mention that I'm disabled. I gave up after 2 months trying to arrange the HV. Eventually my mum gave me Spook as a birthday present - but could only get her by driving 120 miles and paying £225.
When I lived in New Zealand, and we wanted to adopt a cat, we just drove down to the RSPCA and picked out a kitten, and took her home. Why does it have to be so difficult up here?
