They are beautiful. But you were actually right in saying dangerous window blind sord. You should remove the plastic ends of the blind cords as they can cause a hazard to your cat. One of our members here can attest to that. Uabassoon had a very scary and costly operation done for her kitty due to said kitty ingesting and getting stuck one of those plastic ends. So in your cats best interest please remove them.

Again your babies are beautiful.
