Hello! I just recently got my second (last one passed away due to old age) guinea pig baby boy (he is around 5 months) from the pet store. I have had him for little over week. He is very active, very friendly and brave. He is eating pellets with big appetite, also hay and he drinks alot of water. The problem is that i noticed he doesn’t really eat fresh fruits (I feed him carrots, cucumber, bell peppers and lettuce every day also I tried tomatoes too) he only eats lettuce and carrots from fresh veggies. Recently I noticed he only had one lower tooth, I was concerned but he was acting fine and i read it happens sometimes. But today also the second lower tooth broke in half, very close from gums. He haven’t had any trauma while i have had him. I also try to put vitamin C drops in his water but when i put as the label on the vitamin bottle says then he doesn’t drink at all, so i have put 5-7 drops instead of 15, then he is drinking. I'm going to vet on Monday but does anyone know what can cause so young guinea pig to lose both lower teeth? i also noticed he had two bites on his back (he had 4 other guinea pigs in the cage) could it be because he was “fighting” at the store with other pigs? (He is red eyed ginger rex breed)- maybe it counts too..
