A Quiet Critter might land on your desk to watch you work. They don’t mind a gentle pat, but they don't like to be picked up or played with. Most of all, they hate "noisy" voices. If the room gets too loud, the Critters get a "tummy ache" from the noise and must scurry back to the safety of their quiet jar until it is peaceful once more. Where to Buy Quiet Critters in the UK
