We fostered Gigi, aka Phoebe, for just over 4 weeks. She is off to her forever family now. She is a very charming guinea pig who was in our life just the right amount of time. Although, we will miss her squeaks and requests for fresh water. We also discovered that fostering a pet is a great way to gauge if your family is ready for the longterm commitment of taking care of a pet. Try it out before you buy. Better yet, don’t buy, adopt!
