I adopted a 2 week old kitten about a year ago. I hand-raised her. She has been so connected to me since, as you would imagine. Being irresponsible we also adopted a male cat who was a week older than our lovely Meana. We did not neuter Thor until it was too late, so we ended up with 4 lovely kittens.
A horrible accident took one away, but we have 3 beautiful kittens left to love. And Meana was surprisingly a decent mother despite the fact the she did not have one to show her how to do things.
