If anyone has been considering an automatic water fountain but hasn't taken the plunge (pardon the pun) because they are expensive -I paid about $50 for mine- I just stumbled across this one on the Petco website for $17.99! http://www.petco.com/product/109056/PETCO-Automatic-Cat-Water-Fountain.aspx?CoreCat=OnSiteSearch Automatic fountains are great for encouraging your cats to drink more water, which can help prevent dehydration, constipation, urinary tract infections, kidney problems, and just promotes general well-being. Plus, they filter the water and just make it taste better for our spoiled-rotten little kids. I swear by mine. I can't personally vouch for this one, but it got decent reviews and the price is right!
