A few days ago i purchased my guinea pig from petco(not being informed on how petco is).. she seemed quite over weight but i thought she might of just had a poor diet with her previous owners.. i adopted her and she’s been really good these past days besides being really skiddish when we try and pick her up.. she’s starting to eat a lot, and i feel like she’s getting even bigger. Last night she would not move and she kept licking her genital area.. i don’t know how old she is and i know it can really harm them if they are over a year and haven’t had a liter yet.. i just can’t figure out if she’s pregnant and i can’t feel for the babies since she’s so skiddish. she has quite a pear shape, i was wondering if anyone would have an idea of what’s going on ???
