Meet big brother Blue and his sisters Meadow and Little Willow,a family of three blind cats that just got adopted by the family Catherine Magno.

Their story starts just before the Christmas of 2014 when the kittens（小猫）were found in an abandoned house in Dubai.By then they had already lost their sight due to a cat flu that was left untreated by their previous（先前的） owner.After that they came to an animal home.At some point,brother Blue almost got adopted by the previous owner's neighbor,but the poor confused cat couldn’t bear living without his sisters and cried all night while searching for them.Soon they were all united in the animal home until the important night of 19 February 2015,when Catherine took them under her wing.

"I had zero experience having adopted my first ever rescue kitten just a couple of months ago,"Catherine said. "But their story touched my heart so much that I couldn't bear the thought of them being put in a cage for a very long time or even worse."

Catherine was worried about the special needs of her new pet friends:“My worry was that it's going to not only be challenging but also require a lot of adjustments on my part,”but apparently it wasn't that much different.“The only adjustment early on was keeping everything where it was but they are soon adaptive（适应的）.”And as she wonderfully put it:“Blind pets see through their hearts."
