My first girl, bless her, dug holes in the sofa to hide her treasures. She also "pretended" to bury biscuits: she'd carry them to a spot on the broadloom near the baseboard, would dig a "hole", drop her biscuit in, then obsessively push imaginary dirt over it & delicately tamp it down with her nose until she was happy it was well hidden. Then she'd grab the biscuit and eat it.
She only buried a bone in the garden once, spent about 30 minutes at the task and restored the site so painstakingly that it was impossible to tell where she'd disturbed the dirt. It was eerie.
Does anyone have a B that runs & hides in the basement when you BBQ or grill lamb??? I've had two females now who seem afraid of the odour of cooking lamb…maybe they think there's a grass fire on the plains and they're next???
