Adopting Cats

So as I have posted here before, I adopted a stray cat, she was about a year old or sumthin'. Named her Chester coz I thought she was a boy. About 2 months later, I adopted another cat and named her “Snuggle”. She was so pretty and cute I can't get over the fact that she's already gone.

So anyway, I thought Chester and Snuggle was getting along with each other. One of our workers (we own a small business) told me that Chester kept teaching Snuggle to go near the highway. Which was unlikely coz Snuggle was a house kitten.

Chester is a very jealous type of a pet. When I got Snuggle, she was always on the roof and refuses to show herself near us. She's only gonna come back down when it's time for her to eat. She always observed me and Snuggle whenever I pet her (Snuggle). As months passed by, they got along pretty well. I was so happy. And then, I woke up and Snuggle was gone. She got hit by a car. I couldn't even see her body because the worker I mentioned threw her in the grabage truck and acted like it was fucking normal I am still fucking pissed.

Anyway, is it possible for a resident cat to teach a kitten to go near the highway so she'll get hit by the cars and die?

*Chester also started to stay in the house when Snuggle died. Felt like she planned it all along. I don't know what to feel.
