I have had two male chins for 1 year and 6 months and found one dead this evening. I had bought them for my daughters for Christmas and received them 2 months after birth. My family and I haven’t paid much attention to them this morning being that the children returned to school today and I was working. When my daughter went to do her daily cage cleaning is when she noticed one was not moving. It happened suddenly and we don’t know what happened. Yesterday I did cook a Sunday dinner in which the oven was on for hours before I decided to put on the AC in which I’m afraid the chinchilla may have died from a heat stroke. The other chin is fine but seems a bit sad and not his usual self. The two would normally sleep very close together in a hugging position and would play all night long. Can someone please give me some insight on what could have caused the death of one chin? How to care for the other chin being that his buddy is gone? What signs to look for or to make sure the other chin is in good health? My daughter question is how come one died and the other did not?
