Seems as if my 5-month old kittens are getting their big teeth! I noticed they have started to rip apart toys and some other objects, so I checked their mouths and my girl (Christie) seems to suddenly have two teeth (fangs) growing out of the same spot (on each sides). My other 5-month old just has one on each side, like normal (I think he has his adult tooth, but I never noticed him having a double-fang like hers!) Is it okay/normal for a kitten to start having two sets of teeth at once?
