Stainless steel bird cages are loaded with benefits that you should strongly consider before purchasing your next bird cage. The biggest benefits are:
They last a lifetime! - Whereas a powder-coated cage will only last 4-6 years in most cases.
They are much easier to keep sanitary! - They wipe clean easily & can be pressure-washed without damaging the coating.
They carry zero toxins! - Regardless of how "bird safe" a powder-coated cage is, it's still not "safe" for a bird to ingest powder-coating. Not only will you find trace amounts of toxins in the powder-coating of even top brand names of cages, but the powder coating can come off in shards that are not easily digested by birds.
Also note that stainless steel is a very elegant look that compliments the decor of just about any room or space.
