Found another Striped Marsh Frog in the house this morning, the cats alerted me to it again. It's different to the other one, The markings are slightly different and the abdomen is fuller and the back legs seem not as long. Since I've put the cat proof fence 900mm off the boundary fence, there is an little oasis of safety along that 900mm strip for wildlife, especially where it's shaded and I've let the grass and plants take over. I'm guessing this one might be female, and the other one likely male.
