i have 2 male degus that are 5 months old. last night one attacked the other, resulting in a visit to the vet, Shadow is really badly hurt, so the vet said i should keep them separate from now on. i’ve put their cages next to eachother so they can still see and talk to eachother but they seem really upset about being apart. any suggestions on how to keep them happy? toy ideas, etc. would really be appreciated.
