Steve Cash, a popular YouTube personality best known for his "Talking Kitty Cat" video series, died in an apparent suicide Thursday morning, PEOPLE confirms. He was 40.

His "Talking Kitty Cat" series, in which he'd engage in funny "conversations" and situations with his cat Sylvester, featured 69 different videos — the first of which was shared in 2008.
