I like how his failure to capitalize the L drastically changes the meaning of
"for my cat, lover."
As for the child's room comment? It's hard to tell what he could mean that wouldn't be creepy as hell. Maybe he's trying to say that he looks for lost iPads and stolen ketchup bottles in Shield's room...?
-EDIT- oooooh, OK! I read
@0 1 's comment and figured out that Lou meant "you should not search a child's room".
ngl, when I saw that post on Twatter, I legit thought he was bragging about pulling pantyraids on Shield's room, too.
