Slimy Intruders

I've noticed that most of the weird stuff that happens in my house has to do with access from the outside.

Like the time I came home to find that other cats were using Pooja's cat door to themselves into the house and into my bedroom.

Like Pooja's tub excavation project.

Or like the gang of snails that breaks into my house at night.  

They come nearly every night. I have never seen them, but I know, because I find their ghostly, glistening tracks on my living room rug in the morning.  They must be training for the Gastropod Olympics, because the circular trails over the whole rug make it look like they're crawling laps.  Or having a dance party.  Plus, it's got to be more than one snail (or worse, slug  *shudder*), if it can cover that much territory between the time I go to bed and the time I wake up. 

I just hope it's not these nasty things (And seriously, why do all of the most insane things you hear on the news happen in Florida? Is there something in the water?).

The weirdest part is I don't how or where they get in, because I can't find their tracks anywhere but on the rug, and there are no open crevices for them to crawl in through.  The only plausible answer I can come up with is levitation and molecular rearrangement (is that even a thing?).

Anyhow, I've been letting it go on for too long, because the little jerks crawled all over a pair of brand new sandals that I was dumb enough to leave on the rug for a few days.  This means war.

To be continued...

UPDATE:  A line of salt in front of the door totally worked.  I haven't seen any trails in weeks.  Hooray!
