Giant Water Beetle

I was working in my garden and my cat ran up with something in its mouth. The something was sideways and wriggling. Thought, at first, that it was another mouse. When he dropped it I came over to have a look and saw a huge bug. After some coaxing, it made its way into a ziplock baggy so I could bring it in to research on the web.
Judging from the logo on the envelope I think it must have been a little over two inches from snout to tail. They're also called electric bugs because they are attracted to porch lights. Another name is giant toe biter since they have a nasty bite and are usually low enough to attack feet. I guess it's give and take since some people eat them. I'm told they may be dried and put in soup or fried with Thai seasonings. I was happy that my cat and I were not bitten and I let it go in the gully when the cat was looking the other way.
