I have 2 female rats. I noticed one of them has what I really think are bite marks from the other rat. They are in a cage together that is about 2 ft long, 2.5ft. high, and 1.5ft wide (I am estimating)... I know that they do not fight all of the time, because they don't when I am around, although I have heard them 'scuffle'. The other one is just fine. The one that is injured acts just fine, but the other day I noticed a 'fresh bite'. It was a little bit wet looking, and there was some blood. I am hoping it is not some strange skin infection- I am pretty confident that they are bites.
(I probably will run her to the vet to be sure)
What should I do if they are actually bites??? (I have had both of them for about 5 months- they have lived together the whole time, and I got them both at the same time- one from a Petco, and one from a Petsmart)
If I were to get rid of one it would be the one that is doing the biting since she is not very social with people. But then I am concerned that she would not go to a good home... would a bigger cage solve the problem??? (The strange thing is that they still sleep together- and the one that is injured isn't showing any fear of the other one)
