Unfortunately, yes. I have to keep a close eye on my fur posse because they do such things. My RB Peeka loved ribbons and Boo Bear does, too. Puddy will lick off all the adhesive on envelopes if I leave them out. I've been lucky because they've passed in the litterbox what they've eaten. Keep an eye on the litterboxes and, hopefully, she'll leave a "deposit" for you. Please keep us posted on her condition.
