We've seen the occasional chinchilla owner ask if there is any clothing that is appropriate for chinchillas. The quick answer is, “no”.
It is unlikely that if you're comfortable with the temperature of your home that your chinchillas are uncomfortable. Not too hard to believe right? After all, they're covered with some of the densest fur in the animal kingdom. At the same time, if you're warm then you run the risk of having your chinchillas overheat if you put additional layers on them.
With the warnings aside, you still may want to put clothes on your chinchillas perhaps with the intention of taking pictures. If that is your plan, you can use doll clothes since they're likely to be the right size. An alternative for those that are craft-oriented, is to make your own.
Keep in mind that you don't want to make the clothes too tight especially around the neck area. We also recommend that you don't leave your chinchillas unattended so that you can take appropriate measures if they start chewing on the fabric.
If any of you have pictures of your chinchillas in clothes, feel free send us a link. We'd love to see pictures!
