Re: Getting Really Annoyed
Keeping males together especially if there is a significant difference in sizes and they were not raise together from the start (example: siblings) is rarely a good idea.
Not the big rat's fault just something very normal.
Introducing a male to another one can be done if they are the same size however there will likely be some fight at first as well.
Re: Getting Really Annoyed
Man that stinks! Hope your little guy pulls through. I've only kept male littermates together and never have had an issue. Good luck.
Re: Getting Really Annoyed
Never keep breeding males with other males, it's almost a certainty that someone is going to end up like that, sorry for your lil boy :(
My males have zero tolerance for each other and will fight within seconds of hitting the floor in the same area :P
Re: Getting Really Annoyed
I wish I could house males together, they absolutely refuse any other males in their midst :P
