As a Dad who doesn't want more pets, I'd just like to clear something up.
We don't dislike animals. Our heart doesn't grow three sizes when you bring one home and catch us cuddling with it two days later.
I fucking LOVE animals, and I will cuddle the fuck out of anything that would let me, but I also know that nobody else in the house will make sure it's fed and cleaned up after. So, no you can't bring another animal home because I've already got enough on my plate, but when you do it anyway, be prepared for it to be MY little buddy.
