Before I get shouted at, I know they aren’t just for Christmas
but I have 3 weeks off work and Jan/Feb is work quiet time so illl have time at home to settle them in and do all vet stuff. Kids have been desperate for pets (we have horses but they can’t sit on the sofa), and no time for a dog.
So thinking of getting 2 kittens for Christmas, 2 so they can keep each other company when I am at work. Have a large house and garden and a back porch they can come in and out of when I’m out.
But where from? It’s been years since I had a cat and google just shows me a load of backyard breeders selling at £550-£1500 

I’d like them already neutered but understand if I’ll have to get them done, will call RSPCA but loath to as they banned my parents for bringing back a puppy that was attacking my little sister (despite us having 2 dogs from them that were family pets for years).
Just looking for advice and any tips on what I need to do when they come other than flea/worm/vaccination/neuter etc.
