Why is there a need for a place like Irwins?

There are not enough homes for domestic pets in our country and hundreds of thousands are being destroyed every year due to the excess of animals. everybody is on the breeding scene now as a means of making money. We wont even go into the inbreeding issues and resultant genetic defects. puppy mills and backyard breeders are sprouting up everywhere. Animals are abandoned or abused for various reasons. Reasons such as biting there owners guests, digging up the garden killing chickens, escaping,jumping the fence, chewing up everything and other behavioural problems or their owners simply no longer want them, can no longer afford them or are moving so they simply dump them on the side of the street. these dogs become feral and those which are not sterilised add to the numbers of stray animals. Instead of simply killing off the excess animals; solutions need to be established to resolve the route causes of this enormous problem.
