i found a kitten and am holding onto it for a few days to see if I can find its owner before I take it to the rspca, it has a problem with its mouth where the bottom lip isn't sitting properly or has been injured and there is a cut inside the lip, when it eats food gets stuck in the gap. My question is is that a common deformity or injury? Should I be cleaning out the food so it can heal or would cleaning it hurt it further? The kitten doesn't seem hurt or fased at all by it. (The white stuffing the photo is the food its eaten)
