I'm not that much of a pet person sorry to me its like having another kid to clean up after but since I have kids they want furry creatures. We bought my 10yr old daughter a bunny last year. We have been having a debate going on about the bunnies birthday. When we bought her she was a couple of weeks old. So we don't know her official born date. Do most people use the day they got the animal as the birthday (or as my daughter calls it the I gotcha date). Or do people calculate the offically date ??
