On the recommendation of his vet and a small sample package of Cat Attract, we tried it. To make a long story short, IT WORKS! I have ordered it (bought two bottles since I have three cats and three litter boxes) and when I get down to one bottle, will reorder some more.
The basic equation for solving this is: d = vt + (1/2)at2. where d is distance traveled in a certain amount of time (t), v is starting velocity, a is acceleration (must be constant), and t is time. This gives you the distance traveled during a certain amount of time. If you know any 3 of those things, you can plug them in to solve for the 4th.
That is exactly like S = UT + 1/2 AT^2; where U is the initial speed. But instead of meters or feet, linear distance, we use angular distance radians. And we have O = wT + 1/2 aT^2; where w is the initial angular speed (rad/s), T is time (as always), and a = rad/s^2 the angular acceleration.
