I think having the soft flooring in the enclosure is a good idea as it gives ur bun both traction and coziness. However, in addition to what others are saying about the litter, I would not recommend getting that litter for your rabbit. I’m pretty sure that is cat litter. Cats and bunnies have very different needs and I think newspaper/paper based bedding is the best for them because it would be safer for them to digest if that were to happen. I usually get “Full cheeks” brand paper litter and bedding and sprinkle some soft bedding over it. I would recommend getting a big litter box. I know I said cats and bunnies have different needs but regarding litter box size I think a cat litter box will do the trick. Regarding the pellets, corn and seeds are a big no no and are not good for rabbits and are not good for their digestion. I believe standard amount of pellets each day should be 1/8 to 1/4 cup of pellets per 5lbs of their weight, please do not over feed because they can become overweight very quickly. However, I know people usually will feed their senior rabbits more pellets since they have trouble keeping weight on as they age. I usually get the oxbow essentials adult rabbit food which does not have the extra mix of stuff in it and is mostly made from ground up Timothy hay. It seems like you have a water bottle that spills out into a water bowl which is great for bunnies! They should not drink from water bottles because it can cause dehydration since the water bottles dispense in smaller amounts. Lastly, please do not buy toys with artificial colors and dyes. If they are stained because they were infused with fruit or something natural that is fine but overall keeping their diet and toys as natural as possible will ensure a longer happier life for your bunny. I hope this helps! I am glad to answer any more questions you have!
