Frog/toad ID

[Inakayak]

My wife took this photo today. I said it looked like a Fowler's Toad (in SE Michigan). She said it can't be a toad because we're on the third floor and toads don't climb. It is no longer there so we can't look closer.

Does anyone else know what it is?

Thank you.

That big cutie looks like a gray tree frog .
