Ah...mid-summer. The temperature climb high -- and stay there. The air conditioners get turned on -- and stay on. We and our critters drink more and more water to keep our skin from feeling dried out and itchy, keep our mouths and throats from feeling parched.
And so we drink...and drink...and drink. And, well, what goes in must come out. As our critters drink more, even the most diligently maintained cages can develop a faint odor. Having good cleaning supplies when you're changing bedding is one way to keep ahead of the situation. Having a good odor control product under the bedding is another, especially if you have multiple critters.
Ammo-Litter, from Aquarium Pharmaceuticals, is one such odor control product. Fragrance-free, chemical-free, and non-toxic, Ammo-Litter's granules absorb ammonia smells before they have a chance to become airborne. Sprinkle one cup (more or less, depending on the number of critters you have and how big they are) over the cage bottom before putting down a layer of whatever bedding material you use. No matter how much your critters scamper around, the granules stay under the bedding, doing their job.
(I have seen a number of other deodorizing products, but am leery [and so is my vet] of products that are sprayed or sprinkled on top of bedding. Nature's Miracle Litter Treatment can be dusted on the cage floor under the bedding, but it has a scent of its own that I wasn't wild about.)
I've had no trouble finding Ammo-Litter at independent pet supply stores (like Pet Super-bowl in Stratford, CT), but have yet to see it at any of the big chains. It is easily found through online retailers, and the number of pet sites carrying it has grown in the last few months.
