I found the kittens in the back of my husband's car's bumper. They were inside for 2 days and finally dropped out on the 2 nd night. So they followed my husband to worked and came back! However, the mother cat never came to the rescue, so I had no choice but to feed them every 4-5 hrs using syringe. They looked like their eyes just opened. After 7 weeks of syringe feeding, they finally learn to eat solid and also know how to use the kitty litter. Now they are ready for a new home!
