One of our kittens has gone missing

Buttons, the good looking she cat has not been around for food for the past 4 days and it looks like she could have found a boy friend. Unfortunately, Buttons was the only cat that we never managed to catch and to have neutered. As she is now about 9 months old, she could have been seen to by another method, if you get my drift. She'll probably be back with another brude some time in the next few months.
