cheap=not as much as a 360 gallon tank
I'm not real fond of the idea of the kiddie pool, as I have small kids myself, NO WAY I could keep them out of an indoor pool with a toy like my catfish in it....I didn't mean cheap as in $10, although that would be a great idea if I had somewhere to hide it, just cheap enough to keep the cats until the finish work on our tanks is done cause they just don't look comfortable in my 55 right now.
