DD really, really wants a pet of her own. We have two elderly cats already, but DD says she would love an axolotl, a terrapin, a snake or a fish.
I think DD is just about responsible enough to look after an animal (and I would supervise everything carefully anyway). We’re thinking that part of the deal/decision making process would be for her to take sole care of the cats for a month - food, water, litter trays - to see if she is committed and responsible enough. If she passes this test, we’ll agree on a pet and it will be her birthday present. We will research how to properly care for whichever animal we agree on.
I have reservations though. Is six too young? And should we steer her towards a goldfish, since they are likely to be easiest to care for? I’d like to develop her sense of responsibility but at the same time, fish aren’t the most rewarding of pets for children. Maybe we should wait for a couple of years?
