New idea for my deck pots

This year I am trying something different in my deck pots.  We have cats, which we didn't invite, living with us.  They seem to love sleeping in the pots on the deck--thereby killing any flowers I plant, so I have filled them with small shrubs--2 knock-out roses, 2 gold mound spireas and 2 cotoneasters.  I don't think there is room for the cats to get in now and I actually like the look as a change from the usual flowers.

We had a nice rain last night right after most farmers got their corn planted so we are grateful.  That's also why the deck floor looks unusual.  It's still wet in some places.
