My vet told me that neutering Speedy would maybe calm him down and stop the fighting, and if not we could just put him with the girls, but according to my research that doesn’t happen with piggies. So with that I started researching. I'm basically ready to schedule the appointment but I realized something last night. Speedy is a painfully timid and shy piggy, out of the many others in my house I'm the only one he doesn't run from upon sight and it took extremely long to gain that trust. The boys are in one of the quiet back rooms, but the girls are in the high traffic kitchen and are very social. I'm scared than when I put him with the girls that he'll revert back to his old self where he was scared by every little thing and spent most of his time hiding, making it a rare treat to see him out and doing something. Maybe the girls could teach him to be less timid? On top of that Speedy is a little over a year old, weights over 1000 grams, is very bulky and cheerful (as a baby he would run laps like a mad-man and popcorn endlessly), and seems to like Eddy (he’ll wheek if Eddy’s out of the cage too long).
I’m wondering, though, if Eddy would be the better option. Him and his passed cage mate spent a little time in the kitchen and it didn’t seem to bother them, especially since Eddy is curious and brave. From what I’ve seen he seems like he’d get a long with the girls better than Speedy. I’m scared my dominant girl wouldn’t put up with Speedy, that Eddy wouldn’t put up with another bore, and/or that Speedy wouldn’t put up with another bore. Is there anyway to see if two boys would be compatible? The biggest problem with neutering Eddy is that we don’t know his exact age, but we think he’s 4. I’m scared he’s too old to put under anesthesia, he doesn’t seem to be the biggest fan of Speedy so I’m scared he’ll give up in recovery.
Thanks in advance for any suggestions and advice.
Neutering won't change his personality, nor his ability to mate. But you cannot put a neutered male in with females until it has been at least a whole month after the procedure. Apparently guinea pig sperm is really hardy, because it can survive that long in the duct work and he can still impregnate the females even a month after neutering.
On the note of when to put him with the girls, I heard about 3-4 weeks would be good, but the more I learn the more I realize that that might be too soon. I've heard of males impregnating sows after 5 weeks! I just hope the little guy won't get too lonely while he waits.
Thanks again for the feedback :)
However, make SURE that you have a lid on both their cages. Males can be quite acrobatic in their determination to get with the girls even through bars and over the tops of cages. If you let them touch noses through bars, make sure the bars do not have the normal grid square openings. Put another grid through there so the space is very narrow. Some males have been able to impregnate through grid bars.
