Population explosion

We are watching as our yard becomes home to over twenty chip monks, jack rabbits, (too fast to count), cotton tail bunnies, (can't count them either) and Quail, mom's, pop's, teenagers and babies 8-18 hatch at a time. I think they are attracted to the wild flowers, finch bird seed and plain ole good energy. We had two chip monks last year and I counted one bunny. Never seen Jack rabbits like we have now. We have lots of grass to eat for the rabbits and worms in the grass for the birds. I think we have an over population problem. YIKES!! The teenage Quail are "doing it" because all of a sudden we have a lot more young looking parents walking around with 8-15 new babies. They are SO darn cute!! I think they have discovered the Promised Land and we are happy to oblige. However, I'm wondering if this could turn into a problem....but a friend told me that the eagles and bigger birds and other predators thin out the crowd, so not to worry. Our neighborhood cat, CeCe loves to come over and hunt through the wild flowers. Unfortunately, Susan says that he brings back a gift of a chip monk to her at times. Glad I don't witness that!
