Good quality aluminum and steel.What are you feeding those chins in LA??
No, that's a real life breeding collar carved by real life chinchilla teeth. I'd like to say it is a rare occurrence but I've got a can full of them in various states of chewed. Once they get too chewed you can't use them as it allows the females to get into the run.Is this suppose to be a joke???
Wire is a little different. Harder to get a grip on and chew through, though given time some chins will pull on the sides enough to break welds and create holes. Most older breeding runs have patches on them from this. Aluminum is also fairly soft but I've had them go to town on cast iron pans so can't really say that makes a whole lot of difference.Because if it isn't then why do chinchillas remain in their wire cage ???
