I think I’ve mentioned both The Uncanny and Strays in other threads. Both are absurd odes to Killer KITTIES, and… both are free on YouTube right now, just saying. 
I own them both on tape, but the one which really tempts me creep-factor-wise is Whiskers, which I’ve also mentioned before and isn’t even ostensibly horror. It just looks horrifying all around, starting with everyone’s hair. (“Family Comedy.”) That’s also free for the gawking right now. I don’t know if I’m ready, though.
