I am new to the forum so bare with me. I brought home 2 baby guinea pigs yesterday and this morning when I looked at them one had a sticky eye and has been sneezing. I have took them to the vet who gave them an antibiotic injection. But would like any other advice how I can make him more comfortable. Feeding him nuggets and hay. Given him carrot and cherry tomato fresh today. He is eating ok but lethargic and sleeping lots compared to the other one.
