Is it possible for these durable bricks to bash themselves to death? I know rabbits accomplish it but that's often a broken spine somewhere from use of their strong hindlegs into cage walls. Over the holidays the cats got the guinea pig room door open all day, twice (we did attempt to change things the second day), and harassed the guinea pigs. The ones in the open top cages and babies are all alive and acting normal. I didn't fill any food yesterday and when I went to feed them today a sow about 6-8months old was dead by the J feeder with her head in the corner. Her nose was all bloody with no cuts but possibly some missing hair. No other sign. She was in a wire top cage so a cat might have been able to time it just right and hook a claw in a guinea pig through the wire if they ran close by but it wouldn't be a death blow. It would just be an infection risk. She only had other, younger sows in with her and never exposed to a boar so guinea pig aggression or pregnancy complications are not really a possibility. Laying with her head in the corner near the J feeder, bled out through the nose or mouth I can only guess she slammed the front of her face into it and/or the wall and died. :? I've had these guys hit concrete face first from carrying height though and do nothing but bloody a lip or chip a tooth. The other 3 sows are fine, the food and water is the same as everyone else...
