In my latest post, there are five cat photos from Amorgos and one from Crete where I could not previously identify the lens used. I went back to them, studied them, and now have some conclusions. The photograph of a cat lying on a concrete wall was taken with the Leica Summicron-M 50/2. The same lens was used for the cat fight photo (on Superia 200) and for the cat sitting on ground. The photographs of the cat with the man fishing and the cat on the roof of a car were made using the Voigtländer 35/1.4 Nokton SC. I believe this is the case also for the photo of the cat walking behind a fence, but I may be mistaken there.
Anyway, here is one final cat photograph for this year (with the Leica 50/2):
