Tex Avery Rule No. 586—animals are fooled by other animals’ really lame disguises.
Actually, the Hanna-Barbera unit at MGM used this rule, too, but Tex did it with more panache. How about the scene in ‘Ventriloquist Cat’ where Spike pretends to be a sex-pot female cat? (Scott Bradley plays “Frankie and Johnny” in the background). Yes, it fools the male cat, who gives us a comparatively small Avery bulge-eyed take (we do get to see the veins in the eyes) before a bit of cycle animation and then a zoom out of the frame.
The scene gets even more ridiculous with the cat wooing Spike using a voice later associated with whiny ducks in Tom and Jerry cartoons (the duck was voiced by Red Coffey but Harry Lang may be the cat in this cartoon).
The animators in this cartoon are Avery’s standard threesome at the time: Walt Clinton, Mike Lah and Grant Simmons.
