Can I just say well done for finding this forum! You have already proved to be a much more responsible bunny mummy than most! :thumb:
There are loads of really experienced bunny owners on here who will be able to give you loads of advice.
Firstly I would say the term 'dwarf' is a bit misleading, these buns are actually medium sized and can grow to be quite big! If you're looking for a smaller bun a mini-lop or a nethie would probably be the best option. Bunnies can be toilet trained to use a litter tray, and will often do this naturally as they like to do it all in one place. Mine were trained very easily. Bunnies are happy either inside or outside and will not smell so long as you keep on top of the cleaning, which can be quite time consuming!
Secondly, bunnies like to live with other buns! They are social animals so you would be doing your new pet a favour by getting 2, a male and a female pair preferable, both neutered of course!
Thirdly, there are thousands of buns in rescues, of all ages, some already bonded and lots already vaccinated and neutered. It's definitely the best way to go for a new pet!
In relation to why it is hard to look after rabbits I would say it's not hard but you do have to be dedicated. Bunnies can live for 10 years or more and require a lot of care and stimulation in the form of human contact and toys. They are susceptible to various illnesses and will obviously need vetinary care should this arise. They have a very delicate digestive system and must have a staple diet of hay and a supplementary pellet diet. Longer haired varieties will also need to be brushed daily. Also, don't expect your bunny to play and do what you want it to. It will be playful but it will be on the buns terms!
They need a large hutch with attached run outside and plenty of space inside. A bun will be miserable if it is confined to a small space
Rabbits are not a low maintenence pet as some have thought but can bring a lot of happiness if cared for properly.
