Either a mouse or a gerbil. mice, opossums
I don't see how it concerns the chihuahua
a little rat
Usually, no. But in extreme situations when the rat doesn't have anything to eat and it's on the point of starvation then it might eat another rat.
No, because that would be insane. Chihuahua's are omnivores, but they prefer healthy kibble instead of raw meat soaked in blood!
It would actually eat a fat guy then he would eat the catapiller.
they probly would because they eat mice
A chihuahua would not attack another chihuahua for the purpose of killing and eating it, since that would be too risky; one chihuahua is not notably stronger or more deadly than another, so it would be more or less an even fight, which for the purpose of getting a meal, is not worth it. However if we were to butcher a chihuahua and turn it into dog food, another chihuahua could easily eat it. It would just be another form of meat.
Our chihuahua tried to eat one of her puppies. We had to put it with another mom that just had puppies.
I don't think a rat would get that hungry. Sorry.
If it wanted to but I doubt it would.
You would DIE!!
