My home had raised a lot of cats, actually they were born by one cat I brought home at first. Later, they were left only a few of many reasons. And then we need to move to a smaller place, and relatively high, we put the last two cats out. One night after that several days, we heard cat's crying outside, opened the door we saw one of my cats. I don't know why it can back, for mum said had been seen it at 2nd floor, but we live at 7th floor and each unit looks alike, but it can come back, how can it recognize? Maybe you will say my cat is smart, but it is always close its cage door itself then don't know how to open so ask us for help by crying. So, it is smart or stupid?
