Yeah, people tell me the same - that there is no smell in the house. I bet there isn't - Juni makes the craziest noise if the litterbox is not clean when she needs it.

btw, re dog poop - I have seen a documentary about insects (on Animal Planet?) and they showed some insects that were decomposing dog poop in the parks. I guess it was in Australia and they tried it as an experiment, but it worked very well. So, no more cleaning after the dog in the park
