Total Cost Per Year
Freshwater fish: $98
Small animal: $335
These numbers include the basics like food, but some pets will come with more additional expenses than others (dog walkers, crates, pet insurance, etc.), especially when the unexpected crops up.
That said, having a pet comes down to a lot more than numbers, and it can be a great way to help teach your kid about responsibility: to learn to love, be loved and know that her actions affect others.
