I have a 2 acre with 150 cats (left) that I stocked last fall and they have been slow to warm up to the feed. Here in Texas I was able to feed a small amount all year long, and I haven't started seeing them until like mid May.

I'm feeding aquamax 600 at 6:30 AM/7:50PM right now and I never see them when the feeder goes off. Only when I throw out a little AM LMB pellets do I ever see the cats.

I've caught several by chance while bass/bluegill fishing and some are fat, and some haven't really grown much since being introduced.
