I also live in the FLA Panhandle (Panama City) and my bird feeder wasn't drawing very many birds until I bought a live trap and started my "Cat Relocation Program".
Transferred a little over a dozen felines to rural areas before the birds began to show up again.
Got to meet a few irate cat owners...their cats had been on my property and nobody forced them into the trap.
Where I used to live in Gilbert Iowa, cats had the same rule as dogs and they were very strict about both. Seems like cats don't like leashes one bit.
This nest is at the corner of my porch and for years it has been home to 3 or 4 broods a year. Maybe two years ago, I noticed a feral cat on the porch and the babies were gone. For around two years now the nest has been empty.
