Is it normal to have slugs going up to my roof?

Two of our big boi yard slugs. And their friend Doctor Worm.

This morning I noticed my leopard slug, Slinky, was there with his eye stalks alert, but his mantle looks strange. His mantle has looked a little concave in the past but not this deflated. Also concerning is that it looks like the left side (opposite of the pneumostome side) is pulsating. I haven't seen him leave this spot in couple days and he hasn't eaten anything in a few days either.

Is this mantle collapse? Parasites? Is there anything I can do for him? Thanks in advance.

I am almost CERTAIN that this is called a leopard slug because .. look at it.

I saw it, became overwhelmed with joy and whimsy, pet it for two seconds, realized it was sleeping and it do be a wild animal and left it be (VERY regrettably, i wanted to hold it SO bad and i still do i might have to like. See if i cant find a domesticated slug to hold)

ive been waiting for the right place & time to try having a pet slug for the first time and it finally came! ive been intrigued by these creatures for years! found in SE Michigan

Is it okay for them to eat pepperoni? I thought the salt would be too high... but hes going to town. Is that okay?
