This DVD has my cats pawing at the television, trying to catch the birds and squirrels on the screen. They go behind the TV trying to find the critters "inside." One of my cats actually runs into the room whenever he hears the TV go on...he crouches on his belly and stares at the screen hopefully. The length of the two video programs are great--the cats lose interest before the end, usually. But there is a looping option to have them run over and over if you like. The soundtrack of chirping birds and chuckling squirrels is not at all obnoxious to have on in the background while you are doing something else.
If I have any complaints it is that there is a bit too much close-up action (cats like the flitting of birds and hopping of squirrels, which you can only appreciate from a little distance), and the spiders and bees leave them completely cold. If there were an option for 4.5 stars, I would give this DVD that score.
If you have indoor cats who sometimes seem to be bored, this is a GREAT diversion for them. I am glad I bought it and I would recommend it highly to any cat owner.
