Do It Yourself

I finally bought a (flat pack) dresser recently. I love it, but when sliding the drawers in and out there is some minor sticking/resistance and some very slight misalignment. I am perfectly fine with this and actually kind of prefer it (it's nice that the cat can't open them), but I am wondering if over the long term, the resistance will damage the drawer slides in some way ? They're telescoping metal slides, on the side of each drawer, attached with tiny screws. I really like this thing and want to keep it in good shape as long as possible.
