One of my moms cats, her male named Mewton (Muttie, Mew Mew, Mutt, Tubbie, Mootaloop, Fatty Cake, Mutton.....I think that cat has close to 50 names!!) used to LOVE avacado PEELS! He was a stray before she adopted him from the local shealter so perhaps he got a taste for strange things so he could stay alive. We happened to drop a slice of avacado peel on the floor and he ran up to it, grabbed it, and started growling and drooling with his "prize". He is not the type of cat that will just growl...he's about as mean as a sack of potatoes, but he was sure defending his avacodo peel. He ate it all up and wanted more.

The cat I grew up with used to love to chew on the toilet brush. We could not keep him off it!
