Introductions.

Question
I originally i had two male piggys, they were brothers and they lived happily together as they established dominance. the dominant piggy died, leaving max on his own. i read up on what i could and couldnt introduce him to, so i decided to get him neutered so he could have a new friend. i waited a month or so till after he was neutered and i have now to female rescue piggys. i have had them in seperate cages next to each other so they can sniff and talk. the girls seem quite shy, and there didnt appear to be any interaction between them. i put them on neutral ground today together, and i think it went well but id just like to be sure. Max humped the girls quite a lot and chased them around, one of them didnt seem to mind and kept coming to find him again, and the other one seemed quite shy. at one point max was strutting and teeth chattering, a display of dominence i hope and not aggresion? how can i tell..? how many times should i introduce them? and i was intending them all to live in max's larger hutch if all goes well..but i am worried he would be more dominent in there. surely if hes been neutered he should not be trying to hump them to death?
whilst i am asking questions, one of the girls is a little fatter more pear shaped...but only slightly..the shy one..and her feet splay outwards slightly? am i being totally paranoid or is there a chance she is pregnant? i hope its paranoia! they were found at the side of the road so we dont know their history but they are both female and have been checked over.

Thankyou in advance.

Hi Hannah,
First of all, on behalf of all your guinea's, I thank you for rescuing your cavies, you sound like a compassionate, kind person and you've done a great thing for those guinea pigs.
I think if you go to http://www.cavyspirit.com/sociallife.htm it will answer all your questions about introducing the boar to the females, and if it doesn't, feel free to contact me if you still have questions. Remember, guinea pigs should always be kept inside, and it would probably be best to put the three cavies in the females cage to prevent aggression and fighting. And yes, most male guinea pigs will still hump females even after they are nuetered, a lot of times though they will stop after a while.
And no, I don't think you are being paranoid, there is a possibility that your female could be pregnant(how horrible to think that somebody dumped them on the side of the road! They're lucky you found them!). Guinea pigs are pregnant for about 56 to 74 days, how long have you had the females? The signs of pregnancy are increased appetite, the female will drink more, and become pear-shaped, and during the last few weeks you will be able to feel the pups moving inside of her if you put your hand on her belly. For more information on cavy pregnancy's and delivery's, go to
http://www.kindplanet.org/gppregnancy.html . Be sure to give her extra fruits and veggies while she is pregnant(time will tell, she'll get bigger, and you'll know!)she needs extra veggies to help the babies inside of her to grow healthy, and also so her body can make the milk that for the pups. You will also want to give her some alfalfa hay along with her unlimited timothy hay during her pregnancy.
I hope this helps you, and feel free to contact me if you have any other questions!
