Two of the kittens I have been trying to trap look very similar. I have caught Shasta; he was neutered and returned to his family last week. This morning, I trapped another black and white kitten. This is him, immediately below. Right below him is Shasta.
You can see the similarity. I had to consult to of my colleagues at work to help me differentiate them. The cats’ faces are too close for contrast - looking at Shasta’s photograph, I began to doubt that the dot on his nose was permanent, and therefore doubted that I could rely on it for identification. We at last decided that their flanks had differing patterns.
Then, I recalled that the doctor performing the surgeries now tips the ears of the ferals whom he fixes, rather than tattoos them. The efficacy of that practice was demonstrated when I saw that today’s kitten’s ears are intact. Much the better method of knowing cats than trying to find a visual difference in twins. All I have to do now is remember to look for it...
I've named the new one Fresca. I’ll say that he is another boy, and brother to Shasta. He will be fixed today.
