Thank you guys for the replies. I got out my rat health care guide book and we were trying everything - pressure, ice, flour and it just wouldn't stop. I didn't feel comfortable with a tourniquet since I'm not real sure how tight is *too tight*, so we rushed him to the ER vet (the exotic vet is out now). The vet feels it wasn't a bite - but that his toenails got snagged. One came clear off and the other was ripped. They took him in the back for 10-15 min! And then came out and told me that they tried to cauterize it, but want to keep him there for a few hours in case it starts to bleed again. We had applied pressure for 30 min by the time we got there and it had slowed down, but was still bleeding. He was such a trooper, though - even ate some banana while I was holding him! I told the vet I'd rather take Luke home as he would be less stressed there, but he seemed to think that it might start bleeding again and wanted to be able to stop it immediately (we're 15 min away or so). So we drove home and got our travel cage with some things that he loves and drove it back there. We hadn't even grabbed the cage when we flew out the door as we wanted to keep pressure on his little foot. My poor baby...I'll give an update soon. IF you guys think there's any concern with leaving him there, pls don't hesitate to tell me. I had a ferret that was left at an emergency place when she was very sick when I was in highschool and my mom insisted we drive back and get her. It had been 1-2 hours by the time we got there and they hadn't even given her IV fluids as promised. I feel she would have died there and she ended up living for another 5 years (lived to be 10 and died at home in my mom's arms!) so I have a hard time leaving my animals in the care of anyone else, including vets...ugh...I feel so worried, though this is probably not a big deal...
