I've just taken on a new piggie that was abandoned at my workplace, and it's very thin - I've weighed it and my two other guineas for comparison and my 1y/o sow weighs about 950g, my 1y4m castrated boar weighs 1.3kg, and the newbie (which is bigger length-wise than my sow) only weighs 700g. :( I can feel every bump in its spine, all its ribs etc, and it's hard to see quite how emaciated it is because it's a very tufty Abyssinian so the fur makes it look bigger than it is. I'm calling it "it" because we couldn't tell what sex it is - it hasn't got balls, so we thought it was female, but when I introduced it to my two it fought with my boar and tried to hump him, so now I don't know if maybe it is a castrated boar (it pretty much ignored the sow though). It's still in a seperate cage because the three of them wouldn't settle when I put them all in together - after they'd finished strutting around, chasing each other and squabbling, they stayed as far away from each other as possible and kept chattering their teeth until I removed the new one.
So, three questions for experienced pig-keepers:
- Is there anything you can recommend to help put weight on a malnourished guinea pig (I've checked its teeth and they are fine)?
- Is there a surefire way to tell if it's a castrated boar or a sow?
- Should I persevere with introducing it to my existing two, or just keep it in the seperate cage (which is next to theirs, they could chat through the bars if they wanted) to save causing them all stress?
I'll be able to find most of this stuff out from my boss on Monday anyway, but I'm impatient and want to get all the information I can right now. :)
