i have 4 chinchillas
the biggest thing you need to ask yourself about an exotic pet is if you are willing to take care of it because they often have special requirements, and also, can you find a vet capable of treating it if it gets sick? most vets have no idea about exotic animals and will do their best but they honestly dont know what the heck they are doing
for instance, there has not been nearly as much research down with chinchilla sicknesses as with dog sicknesses, and we have had a few issues where the vet really wasnt quite sure what to do and had to try to base it off other rodents, we had one die because of this..but it was our only hope of helping and we didnt know any better at the time
