Kangaroo is an excellent quality meat. We often eat it. Mind you it is prepared for human consumption... not pussy tats. It is very lean with little fat. Tastes good!
Generally cats are selfish in nature and will do whatever they want and dogs are the opposite ( as someone already noted ).
Grab kitty by the scruff of neck and toss outside. It will find some food, no problem.
In Oz many cats have gone ferrile and people go around shooting them. They are said to murder many endangered birds and small marsupials. However, recent research disputes this. Selfish spoiled critters!!!!
