There were no instructions, but the house was easy enough to put him in the sunny garden. But nothing happened.
I emailed the seller but received no answer.
It has been suggested by friends that there is not enough sun in this time of year. Still nothing. I live in the Midlands in the UK please anthing you can recommend?
