Kitties here, kitties there, kitties everywhere

I am owned by two cats. Indoor cats, who seldom come outside. Our neighbour is the official owner of four cats, all of them outdoor cats, who seldom are allowed into the house. Then the owner bought another house and moved out. The cats are now fed by her friend, who moved into her house as a new tenant. The problem is that said friend is away most of the time, so the cats are fed by staffers. Or, in this particular case, not fed at all, I think. One cat lives on a sofa on our terrace since spring, the other ones come running each time I return from work or open the frontdoor to collect the newspapers or hang out the laundry. The big grey one sleeps on top of my hubby´s car. Hubby says he is waiting for him to return in the evening, then jumps onto the car and curls up after some petting. The shy red one sleeps on the doormat, so be careful if you have to leave in a hurry, cat may still be there. The white one slept in our vestibule last night, in the drawer where I had kept the cat food. Haven´t a clue when and how she managed to get into the house. No more cat food in the drawer since cat ate it all, I´ll have to do cat food shopping, should the situation worsen. It´s a shame when someone doesn´t care for his pets! I did already converse with the original owner, she said she thinks that the cats are fed kinda regularly, but I saw the feeding dishes, all of them sticky, on top a mass of flies. No wonder the cats strive for a change of location!
