IF you ask Adam Fulrath who is the love of his life, he will barely blink an eye before responding: Parappa.

Mr. Fulrath, a 37-year-old design director at Time Out New York, keeps five photographs of Parappa, a shorthaired, bicolored, mixed-breed cat, on his desktop. He knows that it might be considered a little weird that a grown man would be so enamored with his kitty, but Mr. Fulrath, who is into video games and comic books and calls himself a “straight, geeky guy,” doesn’t care.

“She’s my primary relationship,” he said.

Mr. Fulrath is one of a growing number of single  and yes, heterosexual  men who seem to be coming out of the cat closet and unabashedly embracing their feline side. To that end, they are posting photographs and videos of their little buddies on YouTube and on Web sites like menandcats.com, and Twittering about them to anyone who will listen.

Indeed, it seems that man’s best friend is no longer a golden retriever, but a cuddly cat named Fluffy. This movement, such as it is, is in direct contrast to the most notable in the recent spate of reports about the relationship between a man and a cat, which were far darker; they focused on a young actor who was recently on trial in New York City for killing his girlfriend’s cat  he said it attacked him  only to have a jury decide after several days that it could not reach a verdict.
