When I had Gromit, my class all came round to the house to meet him. A mini day trip. They asked if I would let him out and as he was a people lover I did so. He just tromped around the lounge and when they asked if they could stroke him I picked him up and they formed an orderly queue and experienced their first touch of a reptile in many cases. We then traipsed through to the downstairs loo to wash our hands. That's why it was a mini day trip. It took ages!
He then wandered off into the other room and launched himself on to the top of the guinea pig's cage (yes, he was a house one.)That woke Sausage up! After more ritual stroking of another of my pets, we all visited the soap and water again.
When we got back to school they all wrote about the 'expedition' and all, but a few, said they wanted to do it again. We didn't though because it was the end of the summer term.
I was asked to take him into work but thought I'd better not as he was prone to racing around and climbing up things like a rocket and I didn't relish the thought of him dangling on the ropes in the gym or off the blinds in the classrooms. 🙄
