Just catching up on [the House Rabbit] thread and saw that someone mentioned litter trays... if you go to Wilkinsons you can get seed trays that are actually heavier and often bigger for £3 - the Black Premium Gravel Tray... they are pretty much unchewable and I think our bunny finds them better to sit in because they are slightly textured as opposed to shiny plastic.
We'll probably stay with our gastronorm,
but that's a good tip.
This is the first time I've felt a bit sad about being kicked out. I enjoyed doing that thread. I hope someone carries on my vital mission of spreading the word about house rabbits.
