3 short stories in Horror movie ?

I watched this horror movie with 3 short stories, first was about a man who was hired to kill a cat in a big manson, which killed all the old residents, second story was about men who got in a fight with some mummy and it killed them, and there is the third story about a man who meets a girl outside a bar, they went to his home, and later in future they got married, had kids, then suddenly she was somekind a creature with wings and their two children were with wings too.
This movie is quite old, from about 1970-1980 I think
