Yes, phthalates have harmful effects in animal studies. Of course, in animal studies, it's common practice to literally replace a portion of the poor animal's food with the chemical in question. One classic example is the artificial sweetener cyclamate. It caused urethral cancer in rats, and that was used to ban the sweetener. But they were also feeding it in such quantity that it was forming crystals in the rats' urethra!
The actual risk from phthalates in normal, as opposed to exaggerated circumstances, is open to debate with much real and junk science supporting either opinion. Google it for all the info you can stand.
