We have had our 2 female piggies who are now 13 weeks old for 4 weeks. They seem happy and run around a lot and wheek excitedly when we put hay in the run. We have tried to get them out to stroke them quite a few times now and one will stay on my daughters lap for about 30 seconds and then runs off, the other will not stay at all and just runs straight off. (We have even tried having food on the laps to get them to stay) I was advised to get guinea pigs as I was told they make very tame friendly pets for children. The guinea pigs at our local farm park will sit on children's laps being stroked for ages and I naïvely thought ours would be the same. Is it because they are still young or is there anything we should be doing differently?
