Nice stories, Did you keep the second kitten?
When we moved here we had a Cat that we brought from England . We now have six! I know its crazy, but we are both soft touches. My sister said that normally the man stops the women becoming a mad cat lady but Guy is as bad if not worse than me.We got the first fromThe Denia cat home, he was in the Costa Blanca news as 'Cat of the week' . A ball of white fluff with a ginger tail. Number two came from The cat lady at Jalon market. He is a very plain looking skinny black and white moggy. She had been taking him to the market every weekend for two months, and no one wanted him. So he became ours. About two months later we went to the market and thought it would be nice to let her know how he was getting on. Big mistake.. as we came home with two more, a beautiful pair of blue eyed strippy kittens. Then at xmas we found a little gray kitten in the road, all wet through and starving.
Now we ignore anything Kitten related as you have to stop somewhere!!
Your right about the feeding, if its dry food, once a day is fine. A small payment would be a good idea if the two people that get together can't work an exchange out.
As for Rats and mice, ours love to bring us presents, Rats, Mice, moths, lizards,birds

Bits of lego, pegs, fircones, twigs, etc.
