Mickey and the butterfly bush

In our -tiny garden we have a Buddleia(Butterfly bush)
It really does what the name suggests apart from growing like a weed on steorids;
Butterflies are helplessly attracted to the flowers.
This would all be fine if it wasn't for the fact that our cat Mickey has developed a taste for fresh
butterfly.
So, on one hand our plant is providing all the butterflies with lots of nectar.
On the other hand there is always a well oiled killing machine lying in wait underneath the bush.
