There are many different reasons for bald spots, but considering your recent battle with fleas, there's a good chance it was due to that. The hair coat can sometimes look worse before it gets better, since the old damaged hair is falling out and the new hair is growing in. If the skin in the bald spot is not red or crusty, then it's likely healthy skin. You may also look closely to see if new hair is growing in - that's a good sign that all is well.
If the skin is looking red and/or crusty, then it may be an infection. These can be caused by bacteria, fungus or mites. A veterinarian will be able to diagnose the cause through an exam and certain tests.
I hope this helps and Sam gets his hair back soon.

It is a well known side effect that can occur when using a spot on. As long as the skin does not turn an angry red, oozes or otherwise looks injured, you do not have to worry, Eventually the hair will regrow. There really is no way to avoid that. You may want to try another brand for cats next time.
