Guinea Pigs/Rumbly Tum


Hi, my guinea pig Monty is around six years old. Lately I have noticed that his stomach keeps rumbling really loudly. So loudly that the first time I thought it was my own stomach! He is not off his food or water at all, and gets plenty of hay and fresh veg every day. The rumbling sound happens quite frequently throughout the day and it's really worrying me. Other than that he seems fine, although sometimes he is quite tired and grumpy, and has started biting me if I go near his chin. I know this sounds like a strange problem, but recent vet check-ups have been fine and I don't know what else to do. It is very unusual for Monty to bite me, I am his best friend! I would appreciate your help and advice.

It sounds like he may have some gas accumulation, just as we do at times. You can use some simethecone drops, given orally. Here in the US it comes under names such as Milocon drops, and is actually just Mylanta for babies. I'm sure if you ask the pharmacist they will be able to show you which product to buy. Give him a drop or two and that may settle the gas. That's how it works for babies.

As for nipping and biting are you sure you don't have anything on your fingers that might smell like food that he may like and is making him try to taste you? I've had that happen in my own caviary, and realized that if I'd been handling a carrot the smell was still there. I found that washing my hands with warm soapy water before picking up my nipping little guy solved the problem.

Monty is an old senior citizen by cavy standards. He may be a little grumpy at times and probably not quite as energetic as he used to be. You've been a good piggy mom for him to have lived so long, so you might just have to be extra patient with him and forgive these little indiscretions.

As is sometimes the case, people in urgent need of information have a higher degree of expectation than those of us as experts are able to give. The experts on this site do their best to give the most accurate and responsible answers possible. We ask that you remember that it is not our intention nor place to criticize the professional advice given by your veterinarian, nor is it appropriate for us to comment on the correctness of a diagnosis made by a licensed physician. Our knowledge is experience based. Although many years of breeding and showing cavies gives me a wealth of experience it cannot change the fact that we as experts are not veterinarians and therefore may occasionally have to reject questions that appear to be asking us to criticize advice given by the licensed professional. Having raised and exhibited cavies for many years I have extensive experience in cavy care and husbandry. I currently have an active breeding program for pedigreed show animals but do not encourage backyard breeding for inexperienced owners. Although I don't encourage breeding for fun I'm always happy to answer any questions from an owner who is in sincere need of help. Pet owners wanting to breed should understand that even experienced breeders have litter losses. The mortality rate is high in cavies. The chance for losing both sow and pups is always present, even with experience. Although this is a site for experts to assist owners, there is no expert in any field who has all the answers. The wisest thing a good expert can know is their limitations. Not having an answer does not diminish one's ability or knowledge. It simply shows that we recognize our limitations and operate within them.


Raised and shown cavies for many years, having aquired my first cavies in the early 1970's as pets. My caviary currently handles 65 + animals in two different breeds and several varieties. Having been in the health care industry as a licensed nurse for 35 years I have hands on experience with care and needs in both humans and cavies. Member of American Rabbit Breeders Association and American Cavy Breeders Association.

Awarded Lifetime Membership in of one of the oldest cavy clubs in the United States, on whose Board I served as Sec/Treas for six years and currently serving as President. Also editor/publisher of the club's quarterly newsletter. We are strong supporters of our youth exhibitors, most of whom are 4H members who are working on cavy projects. Through these projects they become good responsible citizens. We deal with all aspects of showing, breeding, caring for and sharing experiences in the fancy. The cavy fancy is not a new one but in some areas is still relatively unknown. Our goal is to inspire interest in high quality, responsible breeding to improve the species, not just the reproduction of guinea pigs. Our job is to educate owners to help them make the right decisions and choices in the care of their cavies.
