My friends don't really mind how many I have, just as long as they're allowed to come over and pet them

My family, however, generally do. My parents think that 4 pets is a good number and that we shouldn't have any more for a while. In a way though, I'm pretty lucky. No-one else in my whole family, grandparents, aunts and uncles, cousins etc have any pets, nor are intent on having any, and most certainly aren't impressed with my little Tia.
