I have 10 here and it really isn't bad.Are you the only one taking care of your cats?I mean..are you unattached and work all day?Then maybe 5 or 7 might be all.
Just kidding.You know what's best for you.Everyone's sittuation is different.Maybe you could catch it then ask for our help?I'm sure every little bit helps.And maybe someone here will take the kitty.
