Squeaking is also a way to show their affection. It can be a happy sound that guinea pigs make when you are feeding them from your hands, holding them, or cuddling with them. It is possible to say that guinea pigs squeak when they see their favorite person.
Some guinea pigs will squeal when they are experiencing potential pain or they need attention. It can sometimes be that another guinea pig is stealing his favorite spot to eat. Pay attention to your guinea pig if you hear a squeal because it could indicate that they need help from something hurting them.
Whistling: Guinea pigs will often let out a high pitched squeal or whistle, and this noise means your furry friend is excited, perhaps about feeding time or playtime. Purring: Another guinea pig sound is the purr, which may make your guinea pig seem more like a cat.
Shrieking: A piercing, high-pitched squeak called a shriek is a fairly unmistakable call of alarm, fear, or pain from a guinea pig.
This is when your guinea pig releases a rapid streak of squeaks. And, it usually means that they are angry, unhappy or agitated at a certain situation. It`s common for chattering to occur when you first introduce a guinea pig to another, especially in a cage.
Depending on the breed and personality, one guinea pig may enjoy being cuddled straight away, while another may take a few months before it enjoys any human interaction. And then there are those that simply never get used to it at all.
They could be up at two in the morning running around with each other, or asleep at eight in the morning and up again an hour later. It`s safe to say that guinea pigs enjoy the dark at least, but we`d even go as far as to say they prefer the dark!
Talk to your guinea pigs whether they`re in their cage or in your arms. Although they might be too nervous to make much of a sound when you first get them, they will start to recognise and love your voice.
Guinea pigs are social animals who do best with the companionship of another pig. Preventing a solitary guinea pig from becoming lonely and bored is a tall order, even for someone committed to spending a significant amount of time with their animal every day.
Absolutely, guinea pigs can learn to recognize their name, and you can even teach them to come when called. Some guinea pigs will learn much faster than others, but all are capable of learning their name.
Guinea pigs are sociable, chatty creatures who generally have plenty to say, using around 11 different noises to communicate how they`re feeling. In fact, guinea pigs use sounds as a primary means of communication and, since they are herd animals, sounds are also their means of maintaining social rank.
How Do I Know If My Guinea Pig Is Lonely? Trust us, even though your piggy can`t tell you it`s lonely, if it`s living on its own, chances are it is. Without a hutch buddy, a cavy is likely to suffer from boredom and loneliness, which in turn can lead to depression, behavioural problems and even health issues.
Most guinea pigs love spending quality time with their owners, so handling them is enjoyable for all concerned. Once your guinea pig gets to know you, being hand-fed and petted become important parts of their lives. This means it`s actually up to you how much you hold them – you can do so as often as you like.
Guinea pigs are herd animals and really shouldn`t be kept alone. Even if you`re the best owner in the world and handle them every day, they`ll still be lonely without a fellow guinea pig to talk to, so it`s really important to keep guinea pigs together.
They tend to `mouth` their owners while being held, just to see if you`re edible! These are not hard bites, though, and don`t hurt. It`s not aggression, just curiosity. Guinea pigs only use their teeth aggressively if they feel under threat – they are their only means of defence.
Are guinea pigs able to close their eyes? It may be rare to catch your piggy when they`re resting their eyes but it`s possible! Guinea pigs do have eyelids and are therefore able to shut their eyes (even if it`s not a completely normal behavior for them).
Do Guinea Pigs Like To Sleep In The Dark? Even though guinea pigs don`t necessarily sleep at night, they definitely like sleeping in the dark. In the wild, they will find a sheltered spot where they can nap, away from hungry animals.
So “visual stimulation” — the excitement one might feel when viewing the color red, and the calm they may feel with blue — can possibly help your guinea pig stay interested and active in their home environments.
A nose bump is a friendly hello, between piggies or a guinea pig and a human. This is the piggy version of the air kiss or the handshake.
However, with perseverance and love, you can get a guinea pig to trust you and feel relaxed in your presence or when being held. A trusting guinea pig is a lot easier to care for, as they will be less nervous when you need to take them out for nail cutting, bath times and grooming.
Yes! If you are new to owning a guinea pig, the response will not be immediate. As time passes and you bond closer with your piggies, they will eventually learn their own name. Guinea pigs have incredible hearing and will begin to understand the tone and pitch of your voice.
(Keep in mind that guinea pigs are highly social, so it is best to have at least two guinea pigs who get along with each other.)
Typically guinea pigs live for 5-6 years, but some may live longer. Guinea pigs are active up to 20 hours per day, and only sleep for short periods. Guinea pigs are highly social – in the wild they live in close family groups of 5-10 guinea pigs, though several groups may live in close proximity to form a colony.
It`s important to remember that although guinea pigs feel pain, they don`t show any outward signs of it, so they may suffer before you notice they`re sick. If you notice changes in their normal behaviour, these can be an early sign of illness or pain. They may be unwell if they`re: Not eating.

Q. How about a name? Should I decide on a name for my puppy first?
ANSWER : A. Yes, to avoid confusion or disagreement amongst family members, it might be better to select the name of the puppy before he/she comes into the home. Just select a few names and settle on one that everyone can agree on and start calling the puppy by that name as soon as he/she comes. If you use this name from the start, the puppy will become more familiar with the name and will develop more affinity with you and your family. Of course, if you find that the puppy just does not seem suited to the chosen name and you change your mind and decide on a different name, the puppy will recover.

Q. Female guinea pig won’t eat and is lethargic. Tried a bath and hand feeding. She is only 2 and a half years old. HELP ASAP
ANSWER : A. I would strongly recommend to take her to you veterinarian as soon as possible as lethargy and inappetence are very dangerous signs in Guinea Pigs. The list of possible causes unfortunately is very long (Gastrointestinal problems -such as obtructions, gastroenteritis and others- Dental problems, respiratory or urinary infections, abdominal/thoracic tumors and many others) and the signs you noticed are not specific to any disease in particular. The lethargy may be secondary to the inappetence and it is important to treat her immediately before her condition deteriorates.

Hand/syringe feeding could be helpful but the underlying problem has to be promptly recognized.

Q. My guinea pig has diarrhea and is weak and falling over.
ANSWER : A. It sounds like your guinea pig is very sick and needs to be seen by a vet to determine the cause and best treatment. It could be an infection, parasite, metabolic disease ( liver, kidney, etc), or some type of tumor. Please call a vet and have your guinea pig treated.

Q. My guinea pig has a cloudy and goopy eye. There are no local vets to treat him. Any suggestions?
ANSWER : A. I would highly recommend going to the place you purchased the Guinea Pig from and ask for advice. Ask them to verify that there are no veterinarians that see exotics in the area and ask them what they think you should do for the issue. If you can bring in the G-Pig with you and ask for someone at the pet store who knows a lot about G-Pigs. If there is no one in the store who knows about them ask if there will be someone in who knows about them that you can ask questions to and to leave a message with them. If they are of no help try another pet store with the same questions.

Q. What does it mean when my female guinea pig purrs while I pet her?
ANSWER : A. Are you sure it is a she? Male guinea pigs also make this purring noise when they are showing off as males and wooing a female guinea pig. Females can sometimes also make this noise when they are feeling very happy while being petted. So apparently your cavy likes being petted.

Q. I have two problems with my 16 yrs old dog: he’s constipated and has a ear ache. What can I use to relieve these?
ANSWER : A. Constipation is a common problem in dogs that can be due to a number of things. However it is a good idea to make sure the constipation is not actually diarrhea, as some dogs can strain after a bowel movement, making it look like such. If constipation is present, adding a little pumpkin puree or plain yogurt to the diet can help make digestion easier and make stools easier to pass. However if symptoms do not resolve after a few days, it is best to speak with your vet.

For ear aches, it is best to have your vet examine the ear as many things including allergies, ear infections, mites and more can cause ear problems. If the ear is just dirty, then cleaning the ear gently with cotton balls or a clean washcloth and a dog ear cleaning solution can help. Do not use Q-tips as a dog’s ear has a 90-degree turn in it and placing Q-tips in the ear can cause damage to the canal or inner ear. However if the problem persists or cleaning does not help, it is best to seek care.
