I think that perhaps "being cruel to be kind" to promote hay eating needs to be the mantra. Problem is we all want to spoil our pets but sometimes we really aren't doing them any favours. I know Bella cat would love a piece of cheese when she smells it and I find it very difficult not to give in so sometimes I let her have an itsy bitsy shaving. What has happened, though, is that I hardly eat cheese at all now!
