I just don't understand this. I mean I understand that they like chasing after birds and mice and jumping up trees etc but every day I see adverts of so many cats going missing. There are so many cruel people out there who love to abuse cats, as well as people who steal cats to use them as dog bait for their illegal dog fighting activities. There are animals such as foxes who can also harm cats, especially if the cat is very small and the fox is a lot bigger. And then there are also cars and buses which can run them over, and trains too. Also, some people might believe it's a stray cat, and then take it in and keep it for themselves. I just don't get why people let them go outside. Surely if you love your pet, you'd want to keep them safe and protect them and not make them vulnerable to harm and danger? I literally never see dogs out by themselves, and dogs are bigger and far more capable of defending themselves than cats can. So if you wouldn't let your big dog outside, why would you do this to your cat? Considering there's so much danger out there, it can be seen extremely careless and selfish to put them in such danger. And then people cry when their cat goes missing, never to be seen again....
