The social benefits of companionship and the positive physical and psychological effects gained from owning pets, though difficult to quantify in monetary terms, are well documented.
The overwhelming popularity of companion animal ownership has created one of the largest industries in Australia, contributing around $2.2 billion to the economy annually and employing over 30,000 people.
Comparisons of Australian industries show:
Of the total annual expenditure on pets, 60% is spent on dogs and 33% is spent on cats.
The average yearly expenditure for each household owning one or more dogs is $531.00. For each household with one or more cats, the figure is $399.00.

Food for pets accounts for a little over 50% of this expenditure and veterinary services total 21% of money spent by owners.
In assessing the value of the pet care industry to the overall national economy, all States benefit. The market shares of the various States are roughly equivalent to their share of total population.
Exports of processed pet food are significant to Australia's overseas earnings. These exports totalled $204 million in 1994 and showed a 72% increase over 1992 figures.
Exports of pets and pet related products totalled $260 million and again showed significant percentage increases.
The pet industry therefore is a large sector that contributes significantly to Australia's economy. Most importantly, the pet care industry is growing, so the contribution will increase even further.
