I didn't know dogs did that.
But cats have been doing that everywhere for many years!
Something about it attracts them to eating it, I don't know why
When we were kids my cousin and I would purposely feed Midnight the cat, tinsel the day my mom was going to have a big Christmas party, so that by the time the guests came Midnight's backside would be looking very
festive
There wouldn't be anything else stuck to it, just the tinsel hanging halfway out!
My mom would come after me and Regina mad: "Girls! I know you've been feeding tinsel to the cats!"
But then she'd laugh too!
But I've heard many other stories of people whose cats ate tinsel.
