I think I am going to look into the hepa filters for the furnace! I rent, so I will check with my landlord to be certain it is okay. I will pay for them myself, so I would think she would be okay with it.

I also want to look into an air purifier, but that will have to wait until I get my tax refund.

My sweetie just bears through it all when he is over, and for now, I do my best to limit the dander. For the record, he has outdoor allergies also, and if he is around indoor/outdoor cats, he has more serious issues (saw that happen this summer and fall). The longer he is in the house, the worse it seems to be. Poor guy, but God bless him for sticking through it! He also has some issues if he is at his parents house for a period of time and around their dog! So it isn't just cat dander.
