Having a pet is a lovely thing. I would think it's sweet for a man to care for a pet and look after it and it shows that they are sweet and caring, very important traits.
But indoor pets are kind of a turn off for me. Mainly because of the lingering smell of...botty deposits.
Imagine you're on the sofa with a lady friend, she's in the mood. "Oh, What's this stuck on my foot? Oh, oh, a rabbit turd." *mood gone*
