I've had my guinea pig, Ollie, for about 3 years now and she's been with a cat most of her life and that never bother her. We recently gave away my cat and this evening we brought inside my 2 dogs. Since they have come in, Ollie has been very lethargic and won't eat while she's in her cage. I got her out and held her and she ate a carrot and seemed to be herself again, but when I put her back in her cage, she went right back to what she was doing. The house also smells like flea shampoo from the baths I gave my dogs. Is she just scared of the dogs or is she sick?
