One of my mom's chinchillas had to be put to sleep last week... we noticed he was in respiratory distress, having trouble breathing. Turns out some of his teeth were poking into his sinus as well so the poor little guy was suffering and mom decided to have him put to sleep one last time. We buried him in the backyard, near my mom's daffodils. He was 11 years and my mom had had him since I was in high school (I graduated in 2016). I was with her the day she got him, along with Charlie, another chinchilla, who is still alive and healthy. We also still have Jenna, another chinchilla we got later.

Rest in peace, little Boris... we will miss you. Say hello to Sulu and Thumbelina (mine and my sister's childhood hamsters) for me.
