The vet I see is basically "pushes" these medications, saying that a mosquito can get inside or a flea hop a ride.
For awhile I thought it would be fun to have the cats on the balcony, but that would expose them to mosquitoes, so I've x-ed out that idea.
If they stay 100% inside I think the risk is minimal - I'm of the opinion that if a medicine can help you it can harm you - less is better (unfortunately I'm dealing myself with a chronic medical condition that is treated with a whole slew of stuff, but that's my burden) - so I don't want to subject the cats to anything more than is necessary.
