Anyone know what kind of rodent this is?

My cat apparently was quite busy yesterday and this morning I found two dispatched rodents outside. I thought they were your average mice until I looked more closely. I tried to figure this out myself, but I’m stumped so far, but very curious.

The fur was greyish, like an average mouse. However, when you look at the creatures, they look a lot like hamsters. Short tail, maybe an inch and a half long (less than half the body length), and mostly hairless. Small, furry ears like mice, and very long incisors – the odd thing is they appeared to be on the lower mandible, and I’m accustomed to seeing rodents with long upper incisors and shorter lower ones, these rodents seemed to have the reverse. Then, they have these long front claws that remind me of a mole, so obviously these guys dig.

Anyone know? My curiosity is mainly because they look like hamster-mole hybrids and I’m wondering what the hell they are. :)

I live in the East Bay, California, in a somewhat rural area (lots of hills and cow pasture and such).
