I would advise you get your hamster seen again as the vet may need to give her more treatment or different ones. If she is sleeping more and losing weight she is not getting enough nutrients to maintain her needs. There is a risk she will be getting dehydrated. You need to make another appointment
By Hannah James-Roll BVSc MRCVS (Professional Advisor)If your hamster is responding well then you may decide to continue as is. The decision only needs to be made if he is not doing well. Your vet is probably preparing you for the worst.
My hamster was seen by the vet again today, and prescribed Baytril again for 7 days. She is eating and drinking well again, although her lungs are a concern. The vet suggested it may be best to put her to sleep on Monday. Is this not too hasty a decision?
