I have a male pig named Sage..he's about 18 months old. He's always been very active running laps and popcorns throwing litter every where. Today I heard a noise and loooked in and he was trying to climb out of his cage!!! He's never done that before! His cage sits next to where I have 3 girls, one is his sister, He can see them but they're in two separate cages, it's mainly so he doesn't get lonely. He misses his sister alot and I'd really like to have one of them fixed so they can share a cage. Why has he started trying to climb out? I had to return to work so I fixed up a lid for his cage, but my daughter just called and said he DID climb out and thank God he landed in a basket of clothes I had put there under hiis cage for just that reason. I've heard such horror stories about getting pigs neutered or spayed, I live in Illinois near the capitol of Springfield, if anyone knows a good vet in the area. Can they be spayed and neutered safley?
