I have a short haired cat (not sure what breed she is) but she has never shed alot which we have been thankful for... Usually when we brush her we get little to no fur on the brush but recently we have been getting almost brushfulls from her coat and today she came in my room and i was petting her and i noticed big chunks of fur coming out.. Like when i rub my hand along her spine i got a handfull of fur in my hands. Remember this is a cat who has barely shed before. We are just curious, is this some sort of extra coat of fur for the winter thats making her shed more now? Or is it something else?
