i need some help, i got a chipmonk from a local petshop last week, he was very cold and not well at all, so ive kept him in a small carrier with a heat mat under it for warmth, hed get better and get worse again and he has lost ALOT of weight so i brought him to the vet today.

i had an idea he had the flu, but the vet reckons because he was imported from germany a few days before i got him and the stress of that made him get the flu, the vet is also worried its fatal, gave me baytril for him but i want to know is there anything else i can do ro give him to help him along
