One of my cats eats tulle fabric. Not just chewing, e a t i n g.
Also, some of my cats dip their paws in the water bowl before they drink out of it.
Also, one of them likes to hide in crevices and then scare the other cats when they walk by.
They used to lick the dishwasher.
They like to open the cabinet door and sleep on the clean dish rags.
If we leave peppers on the counter, they will take them and hide them places. It took us months to find one of them and it was behind some door we never use.
If you leave a cup with a straw unattended, they will steal the straw and knock over the cup.
One of them likes to rip the legs off of bugs and put the legs under the dining room table.
I love all of them so much. They're the best little weirdos in the world. (By the way, we have six cats)
