Emma's cat food is a hairball formula but with the temperatures rising, she's been shedding more and bathing more. I brush her frequently (she thinks she's being spoiled!) but about once a week lately, she barfs a huge hairball. I know this isn't fun for her. I know I can buy some stuff from the store but is there anything I can give her that I can find in my kitchen? Veggie or olive oil? How do I give it to her? She eats hard food. Thanks in advance!
