Oh, these are great!
It will be better adding location information (link to google maps)
and also you can add these to google maps app on your phone that you can see how many times they have been seen.
Google Maps will give you great advantages, and raise your level. When your reached 5th user level in Local Guide, you can apply for Local Guide Summit in the USA.

and that last note:
Istanbul is full of cats, take some photos of them :)
