Well darn...i went to grab some pups today to feed my hatchlings and the TUB WAS FLOODED. My son had checked on the rats and had pinched the water tube so that the rats could gnaw on it in the tub. I came down this morning to two swimming rats and whole bunch of dead babies....ugh. I feel awful. I'm gonna have to add additional grommets to ensure it never happens again.
Just a word of warning. Don't be a dummy like me...
