I don’t want to be dramatic or anything and worry about nothing, but I am a bit worried about my old guy. We have Buzz who is about 1 year and 6 months old with two younger rats about 6 months. Buzz would be considered the alpha, he does the grooming and will put the babies in their place. Recently the babies have been pinning him down and grooming him. Today they flipped on his back and he struggled for a couple seconds trying to get back up. Does this mean he could be sick and they sense it? Or is it just him getting older? Or something normal? Thank you, I just am a bit concerned for my old guy!
