The sun was shining through the window so the photo is a bit bright and is not exactly the clearest shot, but I think it's still cute.
I also recorded a short video of Muffin in the bathroom. It's so short because I had to stop Sookie from trying to play with her; I was actually more worried about the dog than the guinea pig as I was afraid Muffin was going to bite her snout (and she has a hard bite, I know from experience!)
P.S. Thank you everyone for the well wishes towards my brother. My family has been talking to him, and I think he may also be going to the doctor for extra help in dealing with his issues.
