Rat is ill, Not sure what to do.?
I noticed yesterday that one of my new male rats (got Saturday) seemed lethargic and quieter than the other, he seems to have gotten worse over the night, he's sneezing (not much but a bit) isn't eating as much and it a little dehydrated, He sometimes hunches over and he's fluffed up which I know are all signs of pain in rat, I've booked a vet appointment for tomorrow morning but I'm so worried that it's something, I spoke to someone who knows rat and they said it could be URI from the stress of moving but I'm unsure of what I can do for the morning, I've seen him nibbling on some food and he doesn't mind being held but sits quietly in my lap after sniffing about.
I don't know what to do until the morning, is there anything I can do to help him, I'm so worried.
*something serious
