Ours are strictly indoor, though I must say last year when we brought in the babies, they had fleas. Thank goodness they were kept downstairs. I cleaned and shampooed the carpet every day for a week. I used capstar a couple times ( will kill everything on them for 24 hours...but not eggs). Then I repeated again a couple weeks later. Took about 2 months but they were gone. But thankfully I found them before it got bad. And my upstairs cars were never exposed. I hate fleas. I didnít think it would be a worry if they donít go out. What state are you in? For some reason I thought California.
Well Iím glad the girls are ok and by now youíre forgiven.
