I would imagine they can't read something from the online cattery because the online cattery is protected -- meaning no one can access your account except you and KC. Which is a good thing because none of us would be happy if people could hack our cattery (unless the hacker gave me diamonds or exotic journey -- sighs wishful thinking)
on limited prims, my kitties in my linden house drinking milk are 2d which only takes up 1 prim each. I do sometimes have the occasional kitten running around (lol, sometimes poor baby gets get stuck between the other kitties)

I used to cuddle about 60 cats a day but have been busy lately so most of my cats don't get the milk or the cuddle so love takes a little longer to get to 100%. I'm a little broke so that's ok. I just give milk to those that I paired who need to catch up to their partnr or if they are close to 120 days -- example A is at 80% and B is 40% love and I paired them. I put B on milk -- B will get an extra 4% bump a day to help it catch up to A faster.
