That is not B/W but Sepia or something.
After 40 years I did not realize that, I will go back and redo all my work.
Toning of images has a long history, both in recreating classic B&W looks and to increase permanency of B&W images. They are still considered by most to be B&W. If they are not to your taste that is fine.
As for your image, it's a cute image of two animals.
