I think with glazed ceramics, glass it is easy to disinfect and clean weekly with either bleach or vinegar. Disinfecting metal requires vinegar, wood requires sandpaper, because wood is porous. What about terracotta? I have some terracotta pots I want to give my chinchilla and I wanted to know an effective way to disinfect? Will vinegar also be okay for this?
Also, I know it helps chinchillas teeth when they chew on pumice, wood and paper based materials(cardboard, paper towel rolls) but what about ceramics, glass, metal, terracotta? Do they chew these too, and do they also help with their teething? The reason I ask is that I want to make sure my chinchilla has enough chew toys in his cage, and there are many metal, ceramic, terracotta items in there so I want to know if these count into Po's(my chinchilla!) collection of chew toys. After all, I only want the best for him.
Lastly, is it possible for Po to eat TOO much wood? I give him a paper towel roll but I see that he eats a lot of it, and he also ate a lot of his wooden pine house. I know eating too much PLASTIC will hurt but why is this not the case for wood and cardboard?
