Yes!
Excellent point!
My parents gave me 2 pet mice when I was 12.....don't worry...they were furry black/white adorable pet mice. And I LOVED them, but apparently they were male and female which somehow the store goofed up on and we found out when one mouse starting swelling at the waistline
A few weeks later 10 baby mice were born.
Well the big glass cage had a lousy lid and my cat figured it out, while I was in school she jumped in and killed some of the babies.
Worst than that in their mouse family tree they'd been lab mice and injected with Ovarian cancer. One by one all my females died horrible slow deaths from it.
At age 12 I just wasn't ready for the grief and guilt with all of that.
My parents didn't care, I was left to bury the babies and the ones dead of cancer an all.
I STILL suffer from nightmares bout it to this day!!
