Absolutely. But for info, Viresco is purely biological (we don't use chemicals either) and hasn't harmed us, cats, dogs or even our fish! 'Our' cats are now limited to France, where we have a whole colony of ferals and one non-feral who I think must have been abandoned by her previous owner. She insists on staying with us when we're there. We pay someone to put out cat food for them all when we're away, but I'm sure she's also eating somewhere else because she's getting very portly. We had a cat in England who died a year ago, aged 23 (certainly nothing to do with Viresco!) 'Our' dogs are not our dogs at all, but belong to Pete, who helps in the garden and brings his two dogs to work every day. I'd love to get a dog, but we travel a lot and it doesn't seem fair.
