1977's The Uncanny, Peter Cushing, Ray Milland, and Donald Pleasance slumming and chewing scenery in a cat-based horror anthology film. Nothing too lewd or gory, and it's every bit as silly as it's plot sounds. Mostly, I have full confidence in your ability to fill eighty-nine minutes with cat puns. https://www.youtube.com/watch?v=wzQaoI8F1qA
