We feed our cat Blue Buffalo Weight management and the kibble size is quite small. Previously we fed him Rachel Ray nutrish - also a small kibble size. It doesn’t happen often, but every once in a while he’ll be eating and then stop to bat/paw at his mouth for a broken/chewed piece of kibble stuck typically in his molars. We were at the vet recently and she said his teeth looked good. Should we be concerned with this behavior? Would a larger kibble be better for him? He typically removes it by himself but sometimes if he’s struggling I will assist him. Thanks in advance!
