You walk past your grandfather's taxidermized corpse. Skittles finds an unusual attraction with the body.
You take a few guesses as to why. The first guess was about how cats like dead things for food purposes, but then you think that's dumb. The next thing you guess is that cats are just morbid by nature. Your evidence for this comes from your two friends who are cats. Mew Mew, you know their deal, she loves dead things because she is in fact dead. Meowrage likes dead things because he most simply wants to bring back his mom who died when he was young. This, however, seems like it isn't the case.
Your final and most probable guess is that Skittles has the sense that this man right here, your grandfather, is like family to him, but how much? You cannot say. All you know is that he thinks you're his mother, so your grandfather must be his great grandfather. And from what you can tell from cats, they are all about family.
As you walk by, Skittles takes a few glances at his covered eyes, and sees an infinite cosmos onto himself. Then, he continues to follow you.
