About 5 years ago I had a rat, emma. One night there was a storm on the way and emma's cage was outside but I wasnt home. I rang dad and asked him to go over to my house and put her inside. Now emmas cage was a hard wire cage with a plastic tray. The hard wire outer wanting attached to the tray. Dad went over in the rain and put her inside but when he got inside he noticed the bottom wasnt on and emma wasnt in the cage (she was in the tray). He went outside to see if she was still in the tray but she wasnt, she had run away. We went home and I looked for her that night and the next moring but she was no where to be seen. About 4 or 5 days later my sister went out side and stood on a tarp we had on the ground. When she stood on it she her this squeek sorr of noise. She ran inside to me and said that she thought she had stood on a bird or a mouse under the tarp and killed it. I went out expecting to find nothing. When I lifted the tarp, ther was emma! She was just sitting there and she looked at me as if to say "well hello! Took you long enough!" haha! My sis had just stood on the very edge of her little toe. She was not a scratch on her! So there was this demestic rat, outside for about 4 or 5 days, by her self, with cats hanging around, and she survived and was unharmd!!!! She was so lucky!
