Anyone have a dehumidifier that is not an a/c system but is tied into the HVAC system?

Our walkout basement has just a furnace. There was a heat pump system there originally, but then it failed a few years ago, we had them replace it with just a gas furnace as we hardly ever ran the a/c. And even with the furnace, it's only in use maybe four months of the year. The basement has been fine with just the furnace until this year. This summer was exceptionally humid and we've been noticing some minor (as of now) mildew problems in the basement. I'm thinking of having the HVAC folks install a dry (desiccant) system into our existing system. But I could also go cheaper and just get a standard refrigerant based system and have it drain into an existing floor drain. The issue there is that would have to be in the furnace room, which is also where the litter boxes for our cats are. I'm worried a system like that would not work well in a room that has litter dust in even small amounts.

Looking for suggestions, pointers, and watch-outs.
