One of the most interesting gadgets on the market are laser sensored feeding and water dishes. These have a sensor point that will make them open when the pet is near and will close as soon as they stop perceiving the presence of the pet.
While this might be helpful in terms of preventing kibble getting soggy or moist, allowing fungi colonies to grow on it and can prevent dust and other particles from falling on the pet’s drinking water, there are some disadvantages. These wonderful gadgets are still battery operated and unless you are willing to take on rechargeable batteries (which, by the way, are another GREAT invention) you’ll be using the non-rechargables, which can not only cost more but damage the environment.
Therefore, it might be worth your while to take on just one of these wonderful products. Regardless if you have a dog or a cat, they come in cat and dog appropriate sizes, so using one for the water would give you a heads up and let you know how these wonderful inventions work for your pampered pooch or kitten.
All and all it might be worth your while. Where to buy them? The best prices are, as usual, on auction sites of the like and make of Ebay; though there are others available directly from the pet stores, although they are usually about $5 higher than what you see on the auction sites.
