We have 2 rabbits, I love them so much, but once they die I will never ever own a rabbit again.
They really are hard work, they poo A LOT, which means cleaning their trays daily, their cages will also need cleaning out completely, once/twice a week depending how dirty they are, which includes scraping off poo that they didn’t wanna do in their litter tray, replacing all bedding, they need to eat pretty much 24 hours a day, and not the cheapo rabbit food that looks like dried salad, they need plenty of fresh hay, vegetables and nuggets, if you let them roam in the garden they will eat everything in sight, plants, garden furniture, sheds, door steps and whatever else they desire, they’ll also dig and possibly escape.
They’re not the fluffy, cuddly little things people expect, one of ours enjoys a fuss (not being held, just stroked) the other does not like us touching him at all, he growls and charges at us!
Honestly they’re not the sort of pet you get because your child wants one, at any age, never mind a toddler.
If DC want a fluffy bunny to cuddle, it’s going to have to be a stuffed one.
Trust me, you’ll regret it if you go ahead.
