Most manufacturers have no idea what chinchillas (or many other animals for that fact) need and what will, or will not, hurt them or what is, or is not, good for them.
They do not do the research ... if an animal belongs in a certain family, they think it can have anything the rest of that family can have.
Chinchillas are in the rodent family, look similar to a rabbit crossed with a squirrel, so they "assume" (make three words out of that one "word")
think, no, lack of thought on their part, that chinchillas can have anything the others can have. WRONG!
Pet grade corn is bad for chinchillas, but is often put in the feed made for chinchillas ... there are even "corn wheels" for your chinchillas ... made especially for them ... NOT! Not unless you want a sick chin.
"Deluxe" food has all kind of additives and treats added to the pellets ... they are like ice cream ... tastes good, but not good for your chin.
He will eat all the goodies and leave the stuff that is good for him.
The word "Deluxe" is a selling point to humans, just as the looks of a product are ... but that does not mean they are good for your chin ... it usually means the oppo$ite.
People buy the food, not the pet$, $o they cater to what they think will appeal to humans ... not animals. I have seen "starter kits For Chinchillas" that have a hut made of plastic (plastic is a no-no), the shelves and often the ramps are made of plastic ... chinchillas chew and consume these! Plastic does not dislove and will often cut the insides of a chin. It usually has a plastic tray, plastic tubes or bubbles, and the wires are much to big for the safety of a kit or a chin that is young. They don't know any better ... of if they do ... they think you do not or are to stupid to know ... manufacturers are in it for the $$$$.
The pet stores are just as bad ... they house the chinchillas the same way as the gerbils, rats and hamsters ... chinchillas need normal air flow ... not restricted air-flow. The feed them a generic brand of small animal food. They give them chunks of fresh fruit and veggies. Their food often contains nuts.
Sometimes I wonder
how the little pet store chins survive long enough to get adopted!
Any time odor controllers, added scents and foreign objects are added to a chinchilla product when it is not needed ... It is rarely for the good of the chinchilla, but only for the eye-appeal and nose-appeal of the human. These things can and ususally do mean only trouble for your chinchilla.
I could, and sometimes do, go on and on, but ... I'll rest for now.
