完形填空

I have been keeping 41 pets at home: mice, turtles and rabbits. But golden hanmsters are my favorite. I am always surprised by 42 cute they can be.
It was summer when I first 43 two golden hamsters. They 44 brown, about the size of my hand. When I 45 by, they were cracking melon seeds (嗑瓜子). They did that as 46 as any human! I was so amused (逗乐) that I bought them at once.
The only one who was not happy to see the newcomers was my 47 . She thought 48 would make our home dirty all the time. So I made a 49 for them on the balcony (阳台).
Hamsters always want people to look at them. They try to get noticed by raising the front part of their body, 50 they watch you come and go until you stop and talk to them. Watch out when they start to roller-turn in their cage (笼子). They won’t stop 51 you have tears of laugher!
Hamsters are 52 than you think. One morning several months ago, I found one missing. The side of the cage was much 53 than the hamster and the cage had a lid. How did the little one climb up, open the lid and 54 ? I thought hard. But I’ve 55 found an answer.
