Awe this is really sad, he seemed to be doing fine when Jeremy and I were over there last.. :(
Hugs* To Jr. Goat, it''s hard losing a first pet..
As for getting another rat, I have mice and was told to introduce a new mouse into the cage I should put the mouse in a separate cage next to the other cage for a few days.. To let the mice get use to each other and their scents... This way they don't pounce all over each other trying to figure out who what where and when. lol Hope things work out for you guys..
XOXOXO
