As kitty parents know, cats make all kinds of sounds. My little calico lady, Merritt, is fond of trilling, but my large orange tabby dude, Gabby, is fond of the huff (and annoyed, airy snort — does anyone else’s cat do this?!) and the growl. We adopted Gabby as an abandoned older kitty with an unknown past, so it makes sense that he’s got a few behavioral issues and is more prone to expressing his discontent vocally. But I’ve heard a fair amount of cat growling come from Merritt, too (we recently experienced a case of feline non-recognition aggression that caused her to growl away!).
