I don't think it eats many, there is a shortage of meal size tilapia, the barramindi keep them thinned out. It goes hunting every 10 days to two weeks, but that is out in the palm orchards next door. Rats, mice, frogs, toads and snakes probably make up most of its diet. There are 35 to 40 acres of ill kept orchards to forage in with little chance of encountering either dogs or man.
