What would you think or do about a man who puts cat nip and dry cat food on the bed?

I have 3 cats. I put a flat sheet on our queen bed for sanitary reasons. My husband buys loose cat nip and puts it on the bed. Also he puts (loose) dry cat food on the bed. He thinks this is fine. Now when i go to bed i have to shake out the sheet. He thinks this is fine. What is your opinion on this. I think it is beyond stupid. Our couch has turned into a wool blanket with cat nip. Is this reasonable. Who sleeps in a food trough?
