Small bump-like things on cats may be caused by bites of mites, ticks, fleas and other parasites, or may be neurodermatitis or allergies. You need to check whether there are external parasites on the kitten first. If If there are external parasites, you should bathe and deworm the cat in time, and then see if there is improvement. If not, it is best to take the cat to the pet hospital to check the cause of the disease, and then carry out targeted treatment.
