Guinea pig problem?

Coprophagy (eating the soft cecal feces) is vital to the good health of all cavies as it provides them with necessary nutrients. Cavies may eat the soft cecal feces 150 to 200 times in a day, usually directly from the anus. If an animal is obese or pregnant, they maybe expelled and eaten from the floor. Very young cavies may also eat their mother's soft droppings. Some cavies have been known to snatch cecal feces from other pigs. These feces are supposedly the best ones to feed a sick cavy on antibiotics in order to reinoculate good bacteria into the digestive system. The drier fecal pellets are also used but do not contain as many beneficial bacteria.

The mounting is showing he is the boss of he cage, the teeth chatting on the other hand is not as good a sign and may turn into a problem, he is saying stay away form me. Try the introductions in the bathroom for a small amount of time for the first day then increase it each day increasing it to several hours with shared food and water bowels. on the day you try to put them together in the cage again wash the cage out will with vinegar in water so it has a new smell and doesn't smell like any ones territory to protect.

Yep. They produce whats called caecal pellets, these are softer than regular poops and they usually reingest them as soon as they've passed them. Guinea pigs can't get all the nutrients from their food the first time they eat it, so they eat it twice.

Its perfectly normal, so don;t worry about it

The first guy is right. It is necessary. And they only eat certain ones. Totally normal.

Yes it helps with their digestive system so they can poop easier

Yes At first I was thinking the same thing but it is completly normal

I had two, and they don't because they don't have access to it. But, if guinea pigs do, it is okey for them. They are smart. If it wasn't good for them, they wouldn't do it.

They only eat certain ones, when they need more nutrition they will eat some of their pellets.

Mine does and I got worried and looked I'd up and it said that they should eat some of it. They need those vitamins!! lol.

Yes it helps with their digestive system and nutrition, but they don't eat all of it.
