I just realised recently that I recognise my Scamp's "I'm about to poop" meow. It's quite a different meow to his other "I'm bored" meows, or his "I'm hungry" ones, or his "It's 04:00 in the morning let's all wake up!" meows. This specific meow sounds like a question, and it usually means he'd like either an audience for his poop, or that the litter trays aren't as fully clean as he'd like them to be (I empty them at least once daily but with two cats there are times that they're not always 100% spotless...) I don't think I'd admit to anyone other than a fellow cat person that I recognise my cat's poop meow. Do you have anything you'd like to share that you'd only confess to another cat person?
