Raised bed update

I have a love / hate relationship with next doors cats at the moment. Now I know my raised bed looks like a giant cat litter but really it isn't!
Rollo and fluffy if you read this, please stop digging up my BULBS!!!

I am getting slightly annoyed now. I resorted to putting down some old trellis and plastic mesh the other day but it wasn't big enough and they cleverly just dug in the bits that weren't covered... This has now gone and instead we have some rather unsightly big green netting which is covering everything except the Cordylines and the Narcissus which are just opening in each corner of the bed. We shall see if that stops them!!
