Cat eating more the usual

I have three year old Siberian Cat(one that's in my profile picture),& lately she's been eating more then normal, which concerns me. She's acting normal, not acting more tired,her water intake is the same, stools are normal, she's urinating fine. I haven't been giving her any treats, beside her normal food,& it is getting colder. HCM is comon genetic problem in the siberian, which worries me.Should we see a vet?

My cats always want more to eat when it's colder outside. Even though they are indoor only with the heat on.

My friend has outside barn cats and they eat a TON more in colder weather. Not sure if your cat goes out or not. Your kitty is probably fine but you could call the vet to ease your mind.

She is adorable.
