We recently acquired two new members to our family. Two new guinea pigs, to be exact.
I tried to remain calm in the presence of my two-year-old, who simply loves them. I guided her upstairs, all the while feeling my heart in my throat and wondering how I would explain my bad pet-parenting to the friend who gave them to us. What had I done? Was it bad food? Bad water?
Being a master Googler, I got online and started searching for "twitching guinea pigs." Lo and behold, I found an answer. It's called popcorning, and it's reasonably common--when the guinea pigs are happy or excited.
Either my appearance with their daily food excited them or they are just loving our family. Either way, I felt very relieved to discover we weren't doing anything wrong with them!
Maybe some other time I'll tell you about when they escaped their cage and ran rampant downstairs...
