The vet said she is between 3 and 4 months old. She has been staying at the clinic for about 7 weeks. I first saw her when I took my little tuxedo kitten, Bumper VanStowaway, in for his first set of shots. She was so tiny and sleeping peacefully on a pillow behind the counter. When I took Bumper V.S. back to be fixed, she was still there. My husband absolutely did not want another kitten so I did what most wives would do, I borrowed her from the vet for a half hour so he could fall in love with her. It worked :) So I took her back since I had only borrowed her and picked her up later that afternoon when I picked up Bumper.
