Aggression HELP my piggie got's a odd bump.

[arcangel]

On one of my pig left lift side mouth there is this bump and shes still to new for me to get really close to check. it could be her fur in a different look and she seems fine eating and just munching on some hay. Do piggies have pouchs like hamsters?

No, pigs don't have pouches like hamsters.

You need to catch her and look to see what the bump is. Shoo her into a box if necessary, but get her out, put her in your lap under a good light, and take a look.

There are several possibilities of what it could be, but we need some more info.
-- How old is she?
-- Are you absolutely certain she's a female? (See Sexing Guinea Pigs: How to Sex a Guinea Pig.)
-- Is the lump something stuck in her hair, or is in in her body?
-- If it's not something stuck in the hair, can you move it around, or is it attached to the muscle?
-- Does it seem to be sore?

Is she caged alone or with others? A bump could be an abscess from a bite. I think I'd have her checked by a vet in case it's an abscess, cyst or tumor or some kind.
