DSs really really really really want a cat.
I'm a big lover of garden birds and at the moment we get a good variety of birds in the garden at various points.
There are cat visitors in our garden - mostly feral ones! Which has seemed to deter the birds but they don't visit as often as a cat who lived here would be here iykwim!
Anyway in a nutshell can you still successfully attract birds to your garden if you own a cat (or cats if DSs get there way!)
