Growing up I had the following:
4 cats-Smokey, Puff, Charcoal, Mitzy
1 dog-Lucky
2 guinea pigs- Ann&Dan
2 rats- Quincy&Lucy
3 hamsters
4 gerbils
4 mice
2 mallard ducks-Pecky&Quacky
50+ fish
1 squirrel-Gray
2 box turtles- Bonnie&Clyde
3 small painted turtles
3 hermit crabs
many snakes, lizards, frogs, toads
Adulthood:
3 cats-Storm,Pepper,and Sunny
I may be leaving some out but that's all I can think of for now. The number would have to be over 100 animals in my lifetime.
