I can't say that I'm a cat person or a dog person. I own two cats whom I adore. I would love to get a dog but they require licenses, additional vet visits and you can't leave them alone over a long weekend without a sitter. This doesn't stop me from visiting
Petfinder every once in a while or surfing Web sites featuring local rescues.
One consideration when looking for a new pet is their impact on the environment. An
Australian article rehashes the old cat versus dog debate in a new way. Now, I can' help but feel that the article is slightly biased since I heard that Aussies in general are not fond of cats (is this true?). However, the result is that although dogs are known to have the occasional possum for a meal, cats are the most avid hunters and therefore have the biggest impact on native species.
Obviously keeping a cat indoors will lesson their impact on the environment. One could then argue that a neutered indoor cat requires fewer resources than a dog. I'm afraid that there is no answer to this debate. It call comes down to the owner and how responsible they are for their four-legged friend.
