My son and his GF will help out...esp. at the beginning until the kitties learn the house not terrorizing parrots...not digging up the houseplants...and not letting dogs eat them...etc.

And they will help change kitty litter.

Once we're past the 'young cat' stage and they know the rules, it won't be quite so bad. But in the meantime I'm inclined to be a bit paranoid.
