We use to have a cat that would attack things that weren't there. Than it would hiss at shadows and sprint across the room for no reason. Than again we use to get it high.
We use to force him to eat catnip because he wouldn't eat it voluntarily. We even put it in his food. When we gave him the food he wouldn't eat it. So we just hotboxed him in the bathroom instead. But he eventualy got hit by a car.:( R.I.P. Smokey
