There are tons of stray cats around here. We have one that has decided to adopt us. He came in our house via my youngest son one day and was stubborn about leaving. When we did put him out, he followed my son to the bus stop every morning. He would also greet me outside and follow me, you guessed it--right back into my home. He would throw his whole body in front of me with his paws in the air and his belly face up for petting. When any of us walk around the neighborhood, he might as well be on a leash because he literally walks in step with us. I accepted it early on and let him him, took care of him, etc. Heck, sometimes I have to walk him like a dog (with an imaginary leash) because I'm not sure he goes out enough to pee though I don't see any evidence of him using it in the house. My husband was the last to get on the welcoming wagon but the cat won him over too. Everyday when he comes in the house, the cat waits for him to sit at his desk chair and then welcomes him home. He's old and not very playful but he is very laid back and very sweet. He can always be found laying somewhere next to one of us.
