I'd say The Cat from Outer Space just to suggest something obscure, but I have no memory of this score. I just really liked the movie as a kid...
There's an even more obscure cat film that Schifrin scored, titled 'Eye of the Cat.' It's an excellent horror score of an experimental nature that should be presented on album.
I always liked Schifrin's theme, scores for "T.H.E. CAT."
Seriously, "Charlie, The Lonesome Cougar" and (a second vote for) Barry's "Born Free." Would be curious to hear Sol Kaplan's take on 'cat music' for "Living Free" (any takers? Intrada? Kritzerland?) Lawrence Ashmore was the orchestrator, which tells me the score was recorded in London.
Honorable cat music mention: 'Catspaw" (ST:TOS) - Gerald Fried
I like Robert Folk's SAVAGE HARVEST score from 1981 - the film credits state it was recorded at "EMI, London" (Abbey Road?). ... I wonder if tapes survive. The film itself has fallen into obscurity and is unlikely to receive a DVD or HD release due to other music rights issues - the characters sing a couple of Beatles songs around a piano to take their minds off the marauding lions outside.
