"I bought this cage today for two rats that I ended up getting, unplanned, from one of the feeder bins. They're big boys, so I figured they wouldn't be able to slip out of the bars. Anyway, so far, I have to say I really like it. It seems extremely large to me, probably because I'm used to the size of rats and not guinea pigs, but either way, I'm sure it's spacious for them, too. Built well, I've had similar types of cages and it's been easy to put together and I'm sure it'll be easy to clean. The water bottle, food dish, treats, etc are kind of a nice add in and compared to the prices of other cages, this one is pretty well priced! So good setup, size, good deal for your money. (:"
