My four year old daughter would absolutely love this. She is my nature girl, just like her dad. She tries to catch all sorts of bugs.
Her favourite pets at the moment are snails, easy for her to catch I guess. She names them, feeds them and they seem to end up all over the house.
Well she could have a little enclosure with a jumping spider in it and then she can catch small bugs to feed the jumper 😻
She does have a rudimentary plastic bug enclosure, but not nearly as fancy as yours. Might need to be a daddy daughter project one day soon. Might have to save the link to you post to refer back to for inspiration down the track.
