Your dad was a retard.
Who gets differently gendered rodents?
Retards do.
Like your dad.

My family had two mice and two gerbils once, kept them all in a cage together. Thought they were all male, until one day my mother looks in and goes "... I think that mouse is a girl. And she's pregnant."

Gave birth a few weeks later. Housed them in a different cage. A runt disappeared, and we figured she ate it, but other than that all peachy. Until mother decided to put the female and male together again. Even at like, 10 I knew that was a fucking stupid idea, but she's all "No it's okay they love each other" or something. Then bitch-mouse mauled the other one a bit.

He lived though. Died of old age a good while after. Cute little thing.

My cat keept catching mice a few months ago so i started putting them in a fish tank, had about 12 of them in there and kept throwing them food and what not.
They did not care they slowly consumed all of the mice until only one gladiator mouse survived, after earning his place as king of the fish tank i gave him freedom.

Unnatural selection, nigga.

Everyone with cats should do this. Then we'd slowly breed a race of warrior mice that kick ass.

I let my rats live together. A friend of mine owns a snake.
We have an arrangement.

So we all agree that rodents need to be exterminated, right?
