Cats (big and small) are the only animals that purr. " Why?" is one of the most frequently asked questions when it comes to cats. Purring isn't "speaking"-it's more mysterious. The purr comes from two membrane folds called false vocal cords, that are situated behing the actual vocal cords. Cats purr at 26 cycles per second, the same as an idling diesel engine. Kitty purrs both when she inhales and exhales, all the time keeping her mouth completely closed. Scientists think purring is produced by blood in the large vein in the chest cavity that vibrates and is then maginifed by air in the windpipe.

The laryngeal muscles are responsible for the opening and closing of the glottis (space between the vocal chords), which results in a separation of the vocal chords, and thus the purr sound.
I hope this helps.
