Cat and frog games

For the last couple of weeks the temperature has gone up summer-style and the beasties are aware of it.  Our pond has its annual tenant ... Mr Frog, and our cat is sincerely interested in him.  Maybe they have some kind of chemistry going on as both creatures keep each other on edge.
Whenever the frog starts calling, the cat comes over.  Whenever the cat is sitting at the pond, the frog stops calling.  One way of interpretation is that the frog calls the cat which in turn shows up very confused as the frog is neatly tucked away in the plants ...

However I believe this is not the true dynamic of the relationship.  So now and again, we see the cat running with the frog in his mouth ... cat brings frog to us as if to show off his predator skills.
The frog's role in this is to keep stunningly still and cold.  The latter is not much of a problem anyhow.

So we chase away the cat, carefully pick up the frog and put him on the waterplants after which he quickly paddles away to recover.

Can't help but feel as if they're playing us ... today I had the impression the frog was chuckling.
