Can I use bio spot flea collar and Advantage 2 flea meds on my cats at the same time?

Yes, you can use both of these flea preventatives simultaneously. However, flea collars are notoriously ineffective, so I never recommend them under any circumstance. If Cali is currently having an issue with fleas, you can instead give her an oral Capstar ( http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=10902 ) to kill adult fleas within 30 minutes, and use the Advantage to prevent fleas for a full month. If Cali is not currently experiencing a flea infestation, Advantage alone should be sufficient. Good luck! :-)
