I think there is a way to fix it - simply don’t feed your cat till she is hungry. When so, the only one human who can help her - is you. And of course she’ll come to you to ask for food. When it’s going to happen, give her a treat and pet her. Do it for approximately 5 minutes, don’t forget to...
I have a furminator and I use it about 1-2 times a week, so my cats do not shed as much as they used to. Even though it costs around $50 it’s absolutely worth it!
