Pigs have very robust digestion but they can be poisoned by food just the same as we can, especially botulism.
However, remember pigs are not stupid and they have a sense of smell MUCH MUCH better than a human's and will probably not eat a mouldy food that would harm them.
Remember also that not all mouldy food is bad - e.g. blue cheese!
a guinea pig and a mouse aren't the same the guinea pig must have its own type of food like alphalpha pelets and hamsters should eat seeds,nuts,etc. Seeds and nuts are like poison to a guinea pig if the guinea pig and mouse are just eating alphalpha pelets (not seeds) i would say its ok.
Dont give it as much food
The guinea pig can start eating solid food at 2 days old.
because people could die of eating more pig
it depends! if the mouse had rabies or a bad sickness then the guinea pig coud POSSIBLE die. but not very likely.
They can if they feel like it.
Martha acted like a pig at the party, eating messily and making loud noises while chewing her food.

roasted guinea pig
Just keep a bowl of store bought guinea pig food in your guinea pig's cage and if it gets hungry it can eat out of that. And also you can feed your guinea pig fruits and veggies every now and then. I do the same with my guinea pig, but she seems to have a problem with eating fruits and veggies. :(
"Pigging out" brings to mind a hungry pig rooting around in the food trough, eating whatever it finds. It's an idiom that means you're eating a lot.
It is not against Islam to say 'pig'. Eating pig is sinful in Islam.
