Whatever they are, they are fun. Ty almost always has one crawling around on his hand. He'll play with it for a while then when it stops moving, he finds another.
He's really rough with critters. You should have seen him the other day with the toad he found. I think... it survived.
Austin has caught on to Ty's love for the worms and has now been picking them up and carrying them around like his older brother does --except tighter.
This is his little hand:
I came home from an errand today and Ty and Austin ran over to show me their little pets. Ty, in his cute little boy voice says of Austin's caterpillar:
"Part of it's face broke off, but it can still crawl."
I love that kid, always the optimist.
