I shouldn't say he can't run in it, he did once. All around the floor tied up in pillowcase, but, he couldn't go fast and couldn't go far. I know my cat, he was probably looking for his food bowl. lol. The kids was amused and it made them laugh all the while you could hear that freight train noise, so the walking pillowcase also, took their minds off of it. Animals are less afraid if they can't see what the noise is all about. I know this for a fact. lol, no I don't, lol. But, it sounds good.
I read it in the bible. Noah said it as the animals was boarding, all in pillowcases. The truth it is in there.
That is where I learned this trick. Do you believe me?
