I had one of mine take it from the back side....I was freaking out. Took her 5 hours to get it down and in that time I had called everyone I knew that had BP because I was sure it was stuck....lol
In the end she got it down and believe me...there was NO getting it out to turn it around. There was another time she took it from the end and then spit it out and took it from the front.
Soooooooooooo.....don't worry, they get in a big fat hurry sometimes and and try to swallow wherever they grab it.
