we bought two cats at petco, and one of them had fleas, and so then the other cat got fleas. i thought petco was supposed to take care of that before they sell them? not to mention they gave us the wrong documentation for one of the cats, but they insisted 'no thats your cats info'. they ended up calling us a week later with their correction. i hardly mind that mistake.. i just cant believe the flea issue. now we are battling fleas. User's recommendation: can we really trust petco?
