Pet's that I've owned, borrowed or lost. Some of them were just animals I cared for, many had strong personalities and I bonded with and thus missed when they passed, got lost, or eaten. Plus re-visiting them in pictures brings back memories.
Raindrops on roses and whiskers on kittens, these are a few of my favorite things. Or at least favorite things that have happened to me. Some good, some bad. But if you grow/learn from the bad, then they make you who you are... and thus are my favorite things as well.
