That was an interesting link to the law about cats and the reason the legal status is slightly different to that of dogs.
Cases of cats causing damage or harm to people are far and few between according to the article but for dogs they aren't. That is why dogs are required to be on leads in public whereas a cat isn't.
"But in practice, cases involving damage to property or injury to people by cats are few and far between. Whereas dogs have been known to bite people and do considerable damage, this very rarely happens in the case of cats."
It also highlights the reasons for the laws surrounding pets "including the freedom to exhibit normal and natural behaviour patterns,"
I watched a programme years ago about what would happen if humans just one day died out. Domestic dogs, according to them, would be one of the first to die out. Cats, due to their natural behaviour patterns, would survive for a long time.
After reading that article, it explains what cat owners are trying to say.
