I have to correct something I said about cat hearing range. I think one of my sources was wrong, or I misread it. I thought their hearing maxed at 24 khz, which we can relate to. But Cats have maybe the widest range of any creature, 48 hz to 85 khz. Humans have at best 20 hz to 20 khz, but most of us max out at 15 khz. That is the shimmering overtones of a cymbal. If isolated it sounds like faint distant crickets. I've worked with audio so some of these things mean something to me and I roughly understand the math and science. High frequencies do not propagate as well as low. If you go to an outdoor amplified concert and start walking away from speakers you can easily hear as each set of frequencies drops off until all you hear are lows. Ultra high frequencies do not travel far unless broadcast at very high db levels. A bat sonar emits at 138 db, the level of a jet engine, but we can't hear it at all. Mice use this to talk quietly since the ultra high frequencies they use will not travel far. I'm trying to understand conceptually how such extreme ultra sonic hearing acuity maps to blind cat behaviors but I believe it's more important than I thought, and may account for some of the inexplicable things blind cats do. It is very hard to understand what kind of sensory world 85 khz hearing can enable because we simply don't have access to those spectrums of audio. We can map ranges of frequencies based on initial loudness or db s, for example jet engine level of high frequencies let bats locate large moths at a range up to 12 meters. But cats I think are in general looking for much lower decibel range sound sources, so that high range should in theory be useful at closer distances. This is a sensory realm we cannot understand, we are literally not wired for it. But it may explain one of the tools blind cats have at their disposal.
Loved it... they were having a blast.
Thank you. It was nice to see the little ones play
