Guinea pig Challenges with invisible obstacle and paper cups

Funny reaction of my Guinea pigs to an invisible obstacle. What lengths will my shy piglets go to for treats? I surrounded the guinea pigs with paper cups. Will they be afraid of it's rustling sound? Which of the boys will be smarter and braver? Flash or McQueen? It seems to me that such games are useful for Guinea pigs. This is entertainment, food and mental development of piglets. 0:00 - Challenge: Guinea pigs try to overcome an invisible obstacle 2:23 - Guinea pigs fight for the last piece of cucumber 2:37 - Flash clatters his Hooves so funny, trying to scare McQueen 2:56 - Challenge: Narrow path of paper cups 3:44 - Guinea pig fails 4:25 - Challenge: Tall paper cup obstacle 4:40 - ASMR: Guinea pigs eat zucchini 5:24 - Guinea pig tries to grab vegetables on a skewer #guineapigsFlashandMcQueen #guineapigreaction #cuteguineapigs #petchallenge #guineapiggies #guineapiggames
