I have my dad baby sit my piggies when I clean their cage too. The only downside is when we come to collect them, revealing the trove of accumulated chocolate tic-tacs beneath their bum.
I love guinea pigs. They are absolutely chill; capybaras and guinea pigs seem to be the same animal sized in xs and xl
I had one I used to hold in my arm like a football or a baby. His head would be in the crook of my arm and I'd hold his butt in my hand and he'd drape his back legs over my arm. He would stay like that for hours he was so content
I don't have any pictures of him handy, but he was adorable. Calico colored with short hair up front and long hair in back. And he was a big boi! He wasn't fat, just grew very large
We have two girls of our own (Daisy and Rose). They get plenty to eat, but always act like they're starving. They don't steal food from each other, but they both act like someone is going to steal their food.
Etch had a traumatic youth because he was abused by his siblings (severely: torn ears and scars all over his belly). As such he wouldn't tolerate the presence of any other guinea pigs. My daughter is his herd. He gets along well enough with our girls when he's here now, but they stay in their own pen, so he still has a separation.
I think his time being the only pig in the pen has given him the confidence of a king. He lets food wait until he feels like eating it.
