Bonnie (Candice Rialson) escapes from her brother/pimp onto the streets of L.A. and quickly makes friends with hooker Pat (Teri Guzman). They both get picked up by convertible-driving Dan (Brett Parker) who takes them back to his house while the wife is out. Pat whips out a pistol and she and Bonnie rob him and leave him tied up in the woods. Pat (who tosses Dan's poodle off a cliff when it bites her) ditches Bonnie when she finds out Bonnie told Dan the gun was fake. Bonnie leaves Dan tied up in the woods and hitches a ride with some hippies. While trying to steal an apple, she meets lesbian artist Geraldine (Joan Blackman) who uses her as a model. Art collector Vincent (Ed Bishop) buys the nude painting of Bonnie. When Geraldine gets too possessive and shoots Bonnie's burglar-turned-lover Ron (Matt Green), Bonnie escapes once again; this time into the arms of rich Vincent. Vincent, however, turns out to be not only a collector of art but a collector of females in all their species which he keeps caged in his basement zoo (the titular pets) and imprisons Bonnie for his pleasure. Bonnie will have to channel her wits and her wiles to turn the tables on Vincent and Geraldine. PETS turned out to be quite a surprise viewing. Not exactly PC with lines like "You're not a kitten. You're just a little pussy" but not exactly misogynistic either (Bonnie doesn't seem to know what she wants other than to be free while those who take advantage of her are portrayed as possessive, cruel, and neurotic - including the possessive lesbian stereotype). The 100 minute running time allows for a leisurely 70's pace, exploitable nudity, quotable dialogue, and a loose structure that keeps things unpredictable. Lead Rialson made quite a name for herself in a handful of memorable but obscure exploitation pictures but PETS may be her ultimate showcase.
