There are those who can't seem to understand why others threaten to "rid" those problem cats. Usually some owners of pets. Yet those who have to deal with other's pets, which is what cats are, who continue over and over to destroy and leave filth on other's own private property is a nuisance. There are some that should not own pets, that do not care what is done to neighbors. Those same people are the ones who have no say in what can or can't be done to remove those problems. What happens with these pets come down to the owner. Control them or don't. Would you let your children run free to trash and urinate on other people's property? If so, maybe others will return the favor to you and your home. Since it is apparently no problem there.

Hill's the maker of Science Diet and a lot of prescription dry foods also sponsers and advertizes at Vet Schools nationwide. Science Diet in particular is full of corn. Vets are mostly not trained nutritionists any more than doctors are. Wet food is closer to what wild cats eat then dry is. Domestic cats are not very different biologically than wild cats. Asian wild cats eat mice and birds. They don't drink much water because they get it from their kills. Cats don't have a high thirst drive. Domestic cats feed only dry food are commonly chronically dehydrated. Urinary problems are a huge problem. Dry food is mostly carbs and cats don't process carbs well at all. Dry food is like cat candy which is why many of them love it but obesity is very common in domestic cats in the USA. Lite foods actually have more carbs. Dry food does not clean cat's teeth, they don't chew it in the first place. Their teeth are not designed for chewing. Dry food is much more convenient for cat owners but it isn't best for your cat. Do you think they feed tigers dry food at the zoo? No, they feed them raw meat! BTW Innova EVO and Nature's Variety Raw Instinct are two dry cat foods that do not contain grains. I just bought the Innova and it was only $3 more than Science Diet. (It is taking me longer to train DH than the cats, they'd be thrilled with 100% wet food fed twice a day) Wellness, Felidea, Innova, Nature's Variety are excellent foods but...almost ANY canned food is better than the most expensive dry food. There are grocery store brands that are lower carb than "premium" brands. They might not be organic and do have by products in them but they are better for kitty than 100% dry.

I have had the neighborhood cats use my raised garden beds as their personal litter boxes for the last 29 years. I have tried everything and nothing works for long. They also use the rose and other flower beds too. We have 2.5 acres way up in the Santa Cruz mts and I am use to finding all kinds of animal poo. Usually after my dog has found it and rolled in it or worse! I swear one cat is here more than he/she is at their home. He/she is always sleeping on the deck or driveway or garden and getting a drink from the birdbath. Must like bird flavored water.

Here's what I'd do. Get a dog poop digester such as the Doggy Dooley or a 5-gal bucket with the bottom cut out. Dig a hole a few inches deep to set it in. Dump stuff in there and after a period of time, move the thing and start in a new spot, and cover the old pit with soil. Avoid places where you'll be digging around for at least a year or two. The worms and the soil food web will take care of the rest. I don't think it takes any particular enzymes to digest dog poop, it is fairly similar to human. I think the sewage plant could handle it just fine. It's just not that convenient to get the dog to use the potty!
