Oh my gosh! SO cute. Welcome! I am a bit new here on this website, and also new to having a rabbit myself. I have a lionhead dwarf bunny. So she also has some long fur, but of course not as long as an angora’s fur will be.
Sirius has a litter pan with a grate on it, and her fluffy little bottom stays clean! Thank goodness. I would 100% invest in a litter pan with a grate. Also, heads up, litter pans need to be cleaned so much more often than I originally thought…. Lol. I clean Sirius’s probably every other day, or every two days at most.
Make sure you get your bunny a brush too! And since it’ll have such a long fur, I would also look into and purchase some bath products. Obviously not water ones, as rabbits shouldn’t be bathed in water unless absolutely necessary and nothing else works, but there are some powder pet bath products, ones specifically for bunnies, on the market. As I sit and try to think ahead for you, I think it would be a good idea to get this as you experiment with what kind of litter box your rabbit will have/will take a liking too! Just in case her backside gets messy.
Welcome again! I’ll be excited to see your baby bun when she comes home.(:
