Midnite is balding...?

Okay so if you all remember my cats had fleas. We managed to get them off of the cats and we are in the process of getting them out of the house.

After getting the Advantage II and using it on the cats the fleas were gone and it was amazing. About three weeks later our male cat started getting bald spots. He doesn't seem bothered by them and there is no scabbing but it doesn't look good.

Here are pictures. Please help.

Gosh, I don't have any idea what might be causing this.  Especially if he doesn't appear to be bothered by it.  Was this area heavily infested by the fleas?  You applied the Advantage II between his shoulder blades, right?

Sorry I'm no help.  Maybe be bumping this thread, someone else will have some ideas.

Thanks for responding!! It's not bothering him at all and it's not where the fleas were focusing either. It's really odd.

I definitely put the advantage II in the right spot so I can't figure it out. It's just worrying me because I haven't seen anything like this. Hopefully someone sees this!
