He's so funny, Rick. Maybe he was trying to give you a Father's Day present by constricting for you, since you're his human daddy. Ha ha.
Aren't they so silly when they constrict? Like the mouse isn't dead enough already and you didn't just feed them like "two minutes" before. The little hogs. I mean, I get it when the mom's who just laid eggs do it. They must be famished. I would know. I remember the morning after I delivered my daughter; I was starved. All I could think about was a Big Mac from McDonalds. So my brother in-law went and got one for me, then proceeded to videotape me eating it, complete with "moi, moi, moi" chewing sounds (from him) in the background! What a brat!............As I divert........
But the corns who do it when you just fed them five, or even three days before are so funny.
You're little guy still looks cute. Does this mean that the new viv is working out well and you've had no more escapes into speakers? (Think of it this way; maybe he was just appreciating the music you listen to when he decided to hang out there for a while!)
