I do not like indoor pets, please don't judge me. Two things are a deal breaker for me- I won't even go to someone's house if they have cats, dogs, cigars, or cigarettes, including e-cigarettes that still smell like smoke and give me a sore throat.
I like animals in movies, in pictures, I even watch Animal Planet. What I can't stand is fur on couches, pillows, and clothes. Cat pee does not come out, doggy breath, dog druel, pet droppings, pet stained, chewed or scratched furniture, vet bills, expensive and stinky pet food, and people who cannot afford to feed their kids, yet spend endless amount on their pets. And people who treat a pet like it's an actual human baby.
And I do not want to smell like smoke or breath it in. I used to think "If you can't beat em, join em." And i smoked against my own will. Never again. I'd just rather not "join em" I would strongly rather be alone than to put up with pets or smoke. So that narrows down my dating possibilities- which was already near zero once you take out drunks, druggies, nonchristians, and fake Christians.
