Hi Gigi

Firstly, I am so sorry to hear about your loss.

Its totally natural for a guinea pig to mourn the loss of their friend, just like we would do. The problem is that piggies may not eat for an extended period of time which can cause health problems.

You need to keep your eye on Snowball and if he continues to be withdrawn you will either need to spend lots of time with him yourself but also consider getting him a new friend.
