Answer to this question is yes; chinchillas can eat mealworms if properly prepared and handled. Mealworms provide them with essential amino acids they require for good health.
Mealworms make an excellent supplement to any chinchilla's diet, providing many of the same essential vitamins and minerals found in hay and pellets. However, proper storage techniques must be adhered to so as to avoid contamination with bacteria or parasites that could threaten to spoil them.
Chinchillas have long been hunted in the wild for their fur and meat, and can even attack humans using their powerful front teeth as a natural defense mechanism against predators like hawks, snakes, eagles, or foxes.
Chinchillas don't produce vomit; however, their feces can be examined under a microscope for signs of parasite infestation. A vet may be able to spot mature worms which have developed within your pet's stool in order to make a diagnosis of any potential problems with her diet or health.
Once diagnosed, dewormers are the best way to treat chinchillas for worms. Furthermore, it's crucial that any infected individuals be separated immediately so that their infestation does not spread to other members of your herd and keeps everyone healthy.
