Kitten wanted (Herts area)

One kitten wanted.
Boy or girl.
Must be litter trained, good with other cats and children.
Preferably vet checked, wormed and deflead.
Our budget is about £15.00 ono, the rest of our pennies will be for buying lots of new toys! (who wants hand-me downs eh?!)
We lived in Watford, so would prefer to buy from the surrounding area. We have a garden to play in and aren't located near to any main roads.
I think our little home would be ideal for a little kitten looking for a friendly, loving & lively place to grow up. It'll be quiet during the day, when the children are at school and nursery and i'll be working from home so the kitty doesn't get lonely, so we can cuddle and play without distraction!
At night time, theres a flap so the kitten can go out and explore the garden if they want (day or night), guided by our big girl cat, who's desperate for a friend! If the kitten prefers to stay in,they'll have a nice warm bed where they can dream of mice instead!!
