The mother was caught in a live trap set up so that to exit the crawlspace she had to enter the trap. Then the babies could be fished out from under the building manually. Bobcat kittens, like many wild and domestic species of felines and canines often have blue eyes when they are young. With few exceptions, the blues eyes change to their permanent adult color as they mature.
Here's a pic of one of the babies after it was removed from the crawlspace.
The mother and babies are taken to a rehab facility in East Texas where they will be relocated someplace more suitable and safe for all parties involved.
