If (we) can use kitty-litter like winter ice melt, is it safe to use ice melt like kitty-litter? If yes would it even work?!
No you can't use ice melt as kitty litter.
What you need to realize is that kitty litter does not make the ice melt faster. The reason people use cat litter on ice is to provide traction, not to melt ice. Salt is what melts the ice by lowering its melting point.
NO! The toxins will eat up their poor little paws!
Don't be silly
