When Rocky (my rotty/dachshund mix) developed cataracts I got a bunch of these little lights you can plug in and put them all around the house. It really helped with his sight at night. I'm sure you can find them at a Home Depo type of store. Kathryn Scooter (atb) Rocky (atb) & Sandy (atb) Johnkath2 at verizon.net Sent from my iPad
