My kitten aroumd 6 or 7 weeks old fell off my bed, and i heard him playing around with his toy. Then he came back onto my bed by crawling up, amd was limping on his back paw. And hw seems to be in pain, but not too much to where hes growling or hissing when i touch his paw. And he was still trying to play with my hands. And now hes next to a big pillow and sleeping, and i dont know what i should do about his paw? Can i get any answers please? Does it sound like a sprain?
