My rat's tumor is falling off at the moment and I'm not sure what to do. It's 11:30 pm here the vet I was taking her to next week isn't open and I don't know the reputation of any 24 hour vets in my area. Is there any over the counter medication I can give her for pain? Should I let it fall off and leave her be? Is she going to pass away? Any information is helpful I'm not sure what to do for her. If I take her to a vet will they be able to help her or should she be put to sleep? She's acting like it's not a big deal she seems like she's in a little pain but she let me pick her up and was walking around her cage when I noticed it.
