Slendercat is Flerken species? it's like Marvel Universe cat Goose!

Slendercat is a cat that is raised with SlenderDog in Slenderman's mansion.

The size of the slender cat is not much different from a normal cat.
it has white fur, no eye shape, nose and mouth.
Unlike SlenderDog, SlenderCats have no tentacles on their body's appearance.

But when Slendercat catch prey or run away kids,
The tentacles come out of the mouth and catch the prey.

This is similar to the cat Goose who starred in Captain Marvel.
The cat Goose is a flerken species.
Maybe... Slendercat was a mutant of the Flerken species.
I heard there is.

Anyway, you have to be very careful with the Slender Cat. If you touch it like you're cute, you can lose your eyes like Nick Fury.
