A solution to keep the cat tent from sliding, would be to put a piece of the rubbery mat that people put under throw rugs to keep from sliding...they kinda have a waffled pattern to them...i have seem them as placemats too, so you could buy one of them too, to put under it...if you are unsure what i am talking about, i can look online...but it should work...

BTW, your pets are very lucky to have a mom like you...they look very comfy on there new beds!!
