So sad!
You clearly did all you could for the kitten. I have held an animal while it died on a couple of occasions in my life as an adult.
I don't think I could have kept it together as a child. What a strong little man you guys are raising!Sorry for your loss. It's never easy letting go of a pet no matter how long you've had them. It's even harder to do with kids.
Now you'll have to spoil the other kitten twice as much.
yea now the kids don't leave that other kitten alone. yea it was hard for my oldest. I think my youngest was just crying because his brother was because the next day he didn't even care I don't think.
