Tallest...

Erm, I'm not sure. Possibly be an elephant.

Smallest would be mouse.

Tallest: Giraffe (zoo)
Smallest: Probably a lizard but I forget his proper name.

It was about the size of my knuckle to the end of my finger. So, very, very small.

Tallest- Giraffes at Belle Vue zoo Manchester about 1958 .My parents took my sister and me out 'shopping' one Saturday but  it was really a surprise treat for us.The zoo is now closed  but at the time visitors were allowed right up close to some animals.It was amazing standing and touching the giraffes and elephants.

Smallest- Probably a blooming mouse that invaded our house.
