Please help identify

[Maermuis]

hello
Very similar to the 'snake in garage' thread, but thought it better to start a new one:

I find strange droppings in my garden area (Parkhurst Johannesburg).

By now I have identified gecko's poo, of which there are lots, but the last 2 puzzles me- see pictures.

These look way too big for a rat?

We have a small fish pond and there are a few frogs in hiding around it, but not sure re their poo.

Will appreciate some help, thanks
