I like the crazy cat lady on the Simpsons. My wife and I are joking that her mother is turning into one. All the strays flock to her door because she feeds them. Them they multiply. Sigh.
Definitely an obsessive behavior, but it's not the usual kind of thing that gets diagnosed as OCD. I also find that people with a preponderence of pets often, but not always, have personality issues, like avoidant personality disorder or narcissistic personality disorder. The avoidant person is uncomfortable around people, so pets are easier to deal with. The narcissist will prefer the company of pets to people because the pets give the unconditional love and acceptance that the narcissist secretly craves.
