Hmmm what have we got:
Various fish in various rooms.
The normal mass of noisy squirrels and pidgeons.
Crows ripping a beautiful and huge green lawn to pieces. :(
A tank of giant snails in Science.
At one point we had a load of trout the kids bred and apparently released into the Wandle. Hundreds of the things!
Mice (what school doesn't after break times).
Various neighbouring cats that come to catch said mice and be fussed by the kids and staff alike. Including a big monster of a cat who looks old and grumpy!
Animals? Do the kids count???
Well, only some of them anyway....:D
One of our science teachers has a large snail. Called Shelly.
one of my schools has a praying mantis and another has some hamsters thats about it
