Hi all, newcomer here.
I acquired three African Pygmy Mice several months ago which I named Noodle, Chickpea and Butterbean. From the start it was quite clear Noodle was very dominant and picked on Butterbean who was very small and frail, but I never saw any blood being drawn so kept an eye on them and hoped it would settle down.
After a while it seemed to but then Butterbean started acting strangely and keeping away from the others. A few days after this I sadly found her dead. I didn't know what caused it but thought perhaps she had been ill and had isolated herself because of this.
A month later Chickpea is doing exactly the same thing. This time I managed to catch her in a glass jar and take a look. She's got what looks like a wound on her throat. Now I'm worried that Butterbean was killed by Noodle and Chickpea is in danger. I will probably separate them, but they're very social animals and I worry that doing that will leave them both depressed. Up until now as a pair they've been fine, always sleeping together and grooming one another.
At a loss here. Advice would be greatly appreciated!
