Oh heck - yes Kay our RB - Kisi was a Meezer and she ATE wool.
It was unbelievable the stuff she chewed through in her 7 years.
Sweaters, scarves. hats. BLANKETS!!, gloves - literally anything she could lay her teeth on and in!!
We mentioned it to the vet and she said - yes she'd heard of it but had never met a wool chewing cat before!
It never harmed her - mind you the litter box was often a very colourful sight!!!
The girls learned at a very early age - DON'T leave anything on the floor!!
