I hit a home run with my pet store kitten. He was donated by a lady whose cat just had kittens (about 8 weeks old). So, it probably wasn't the typical pet store experience.
It's hard to describe, but I've never made a connection with a pet like this before. It just felt right, and nearly 6 years later, he's the coolest pet I've ever owned.
