Biting

Very rarely will a guinea pig ever bite. Normally, when guinea pigs bite, they are trying to tell you something, and is one of the ways guinea pigs communicate with people. However, guinea pigs virtually never bite people out of malice. Also, guinea pigs more nip or nibble, rather than actually biting.  

 

Why a healthy, normal guinea pig might bite, nip, or nibble:
If a guinea pig is being held or carried a certain way, they may not feel safe or secure, so they may try to nip the person they are being held by to let them know of their discontent. It is very often just a nip, but if there are other things that may be causing stress, it may be a little harder than that. To make a guinea pig feel secure when you are holding him or her, hold them close to your body and use a towel or something else to wrap them in, and try not to let them know they are in the air. If a child is bit, they may, unintentionally, be holding the guinea pig incorrectly. See our handling page for more information. If a guinea pig is not yet a total 'lap pet' and not 100% used to being held and they have been held for a while, this might be a way of telling you to put them back in their cage. Guinea pigs, on average, need to empty their bladder every 15-20 minutes, so look for signs if holding them that long so that nipping is prevented. A guinea pig might be sensitive in a certain area, typically around their bottom, or if they have a parasite such as mites or some other illness or condition, they may not like to be held. This is why guinea pigs need an annual vet check-up. Some other reasons are grumpiness from being in a small cage, trying to groom you, was pet against the lay of his hair, is a baby, or going through adolescence.
