Okay, this is going to be kind of stupid, but bear with me.

The only thing I remember about this manga is one panel of a cat emitting "love me beams." The manga's not about cats in any way, some character just happened to have a pet cat that looks cute. I remembered this scene after a discussion with a friend about unusual onomatopoeia in manga. "Love me beams" qualifies, no? :haha

EDIT: Months after the fact, I found it. It's from Cafe Latte Rhapsody. Just as cute as I remembered. 😀 'Cept they were actually "Care For Me beams."
