spend the extra bucks to get powder coated.. otherwise you'll have to worry about rusting, etc... I have two martin's RUUD cages, both powder coated.. well worth it too. One is 2 years old and I've never had a problem with it being chewed or rubbed off... I can't say the same for other brands of cages though. The powder coating on martin cages is baked on
2 rats, 2 mini rex bunnies, 2 cats, 1 prairie dog, 4 species breeding millipedes, 23 various different species tarantulas, 2 Heteropoda davidbowie huntsman spiders, 3 Liocheles australasiae scorps, 20+ Hogna helluo wolf spiderlings, etc.
spiders are addictive... and super easy to care for!
