I noticed today one kitten is smaller then the others, there is actually two smaller then the others but im more concerned with the smallest. He looks for a nipple but i think the others beat him to it. I was wondering if I should guide him to one? Or should I wait? Im not sure if I should intervine with this little guy, I wish I could get a pic so I could show you the differnece, he doesnt look unhealthy just smaller, probly the runt.What should I do?
