BBC presenter Chris Packham says 'there are too many cats in the UK'.

The Cat Protection League say there are 'no reliable research about the effects of their hunting habits on declining numbers of birds and small mammals', although they recognise that cats are 'naturally predatory animals.'

They largely agree with Packham's suggested thoughts on collars, keeping cats indoors and neutering, and like the BBC presenter, suggest pet owners should value their garden more.

They believe bird feed should be left on bird tables in gardens, rather than on the ground, and added that the trapping, neutering and releasing of feral cats might also keep their numbers in check..
