Okay thank you! I'll check later to see how big the spaces are, I have a old Guinea pig cage and a old bird cage that are in new condition, together they would be a really big cage, and if I remember the spaces were only about quarter of an inch, the same as my hamster cage, I also have some zip ties and wire cutters already. If it dosnt work I'll probably just go buy a big rat cage, but I'll see what I can do first with what I've got
