Cage has good access from the top - but not very good access at the bottom door - badly positioned. Good for bucks - lots of floor space. Good for large does, not suitable for kittens.
Cage has good access - large bottom door - whole top opens up, smaller door on the front on the top level. Wide bars - not suitable for small does or kittens. Doesn't come with extra shelves - but shelves can be made/put in easily.
