Please stop buying animals! Do not buy a rabbit!!! I have two amazing rabbits, they are not cuddly and definitely they will not fit in that cage! Rabbits can live for 10 years.
I've ignorantly bought a hamster cage that, although recommended, was vastly undersized. You know what I did? I bought an adequate sized cage.
I am really passionate about animal/pet welfare, so this sort of thing really upsets me. I have seen it so much of it the reptile community and the consequences of poor husbandry. Pets are expensive, it's not just the price of the pet, it's the lifestyle support afterwards, when my hamster needed the vet, you know what I did? I took it despite it "only living 2 years" and costing a small percentage of the vets fee.
It makes me wonder if the pet trade should vastly increase pet prices so people pay it the respect they deserve, like for example, so of the most difficult reptiles are by far the cheapest to buy, so people buy with out the ability to maintain its immediate or long term care needs. if the animal was 6x the price, in keeping with its long term care needs, then it's more likely people will only buy if they are able to maintain those care needs.
But I'm off on a rant.
But the bigger cage, don't get a rabbit, just because pets at home sell it doesn't mean it's right or humane.
