Hello All. Ever since I lost my kitty to cancer, my house seems so empty. I've been thinking of adopting another cat (or maybe two).
Previously, I wasn't looking for a pet, but a friend's newly adopted cat unexpectedly turned out to be pregnant, so I took on one of those kittens. I lived in a tiny, rented flat at the time so could only take one. We had nearly 2 decades of happy times together and I miss her so much.
I now own a 3 bed house with enclosed garden, so thinking of adopting 2 cats. I would like to adopt from a rescue, but I've no experience of this. They all seem to have a different process, but similar fees. Some want home interviews, some don't. Personally, I think the home interview sounds a good idea as they can see where the cats are going, but I guess they don't all have the resources to do that? So far I've had a glance at the RSPCA, Blue Cross, Cat Protection and Battersea websites. I think there are a few local places, but their websites are not up to date and I don't know if they are as 'regulated' as the larger places? I'm not sure which is best.
Also, I keep seeing cats with FIV. I wouldn't mind adopting one of these, but would I be able to get insurance for them? Has anyone had experience of this? I've never heard of FIV before, so absolutely no idea what to expect there other than what I'm reading online, but I can't find anything about being able to get insurance and if the cat will have a lot of health problems, tbh I couldn't afford that without insurance (especially if I got 2 with FIV).
Finally, as I said, my previous cat happened to come to me, I didn't 'choose' her per se. Now I'm finding it hard to choose a cat from the vast numbers I see on various websites. How do you pick one (or two)? If I could, I would adopt them all which obviously isn't possible, so any advice on how to choose my new cat/s? How did you know yours was 'the one'? 
Thank you for your help.
