My piggies are so much bigger now! They're still small for cavies... I think, but their mom was the same way. They're otherwise plump and happy, though I have been very careful not to give too much.
There's not a ton to report. My sister is the official cavy charmer. She can get them all stretched out and half-asleep in her lap in just a few moments, even when they're together. If they're together on my lap, they just crawl all over each other and talk to eachother ceaselessly.
