We had a Blue Tongue Lizard as well which are good as they eat the snails but haven't seen that lately. The cats are a problem for the wild life. It is getting colder so the Cockatoos have finished the nuts and the Fruit Bats are not making a mess like they do when it is warmer. They ate most of our Quinces and Mandarins. They do not seem to like Oranges maybe not as sweet.
Shame they don't eat the Red Backs the wet weather we have had has brought on an abundance of the pests. They are your Black Widows. A bite can make one quite sick.
We never get the place sprayed as it is not good for any living thing. Frogs we have a variety I call Bonking Frogs for two reasons one obvious as they are always at it and second they make a bonking sound all night, Annoys the neighbors but I am used to the sound now.
The pleasure of living in an Australian suburb, at least the possums are reasonably quite as long as they don't get in the roof cavity.
