While I was feeding and cleaning the rats today, I noticed that one of the females was sitting on only a few babies (and I counted 15 the night before.) Then I noticed a mountain of pine shavings in the corner of the tub, and saw some movement. Almost all of the babies had been burried alive. I was surprised they were even living.
Why would they do this? After I removed the babies I watched them again kick up pine shavings---and once again bury the rat babies alive.
What the hell?
