Yeah you can, as long as you keep the water you use at a warm tempurature, dont use a hairdryer or anything because it will scare it and may cause frustration, i'd just use a towel to dry them n keep them warm =) hope this helped
It depends how cold it is. If you can go outside in a short sleeve shirt and not be cold, it is probably OK for your guinea pig. If it's very cold though, don't take the guinea pig out...even in a blanket!
yes but only in the summer as if the guinea pig gets too cold i the winter it will die and by the way you will need a huch not a cage as a cage will get too much wind as it has no private bit or shelter and your guinea pig will get wet !
You can feed them both guinea pig food. Don't feed the guinea pig the rabbit food or it will be sick. Rabbits are ok on guinea pig food.
Yes, tomatoes are great for guinea pigs.
yes its ok to give your pig grains but try not to give it too many.
Yes
Not if a guinea-pig eats it, as you have put in the question. It's okay if a guinea-pig chews a piece of fabric, because it will grind their teeth down, which is a good thing.
It depends. They certainly wont be aggresive, but if you do, make sure to spay and nueter them.
no if you feed them it, they have 99% of dieing
If the guinea pig is just roaming around the house without protection, then probably. if it's in a locked cage, then it should be ok. a little scared, but ok.
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.
guinea pigs dont fart, they have no way to remove air from their bodies.
