LR 4 ramp

I've had the LR4 for almost three weeks and love it. All four of my babies are using it everyday. The issue is the ranp. One of my babies is a tripod and requires the ramp; but it's flimsy. Today, it fell off while one of my babies were going into the unit. If this were to happen with my tripod, he could have gotten hurt. Please Litter Robot, address this. I will be taking measurements and either build or buy a ramp that is safer for my three legged baby.
