Cat behavior

I volunteer one day a week at a Humane Society taking care of cats. I am amazed at the social pecking order among animals. There is usually one dominant cat in each room. There are some cats that are food hoarders and don't like to share. There is one cat that was feral; which means she was found outside. She hated her tail or backside being touched. She has been there about five months and now and finally someone can touch her tail or back side without being scratched or bitten. Some cats like to sit next to you or on your lap; others can care less that you are there. There is one cat that always uses the litter box after I clean it. It's like she's saying, "Thank you for flushing I've been holding it in." My children love the energy of the kittens and teenage cats. It never seizes to amaze me how high and far they can jump. The kittens love string toys, pouncing and climbing. My children love coming with me and loving on the cats. They hope I never stop volunteering there. I'm thankful they love animals too!
