I have gave my 15 week old kitten a spot on treatment and he's been sick and had the runs. Is this normal?

It can happen, some spot ons can create such side effects, in most cases it only happens up to 24 hours after you applied it. If it continues more than that, your kitten might be suffering from a condition non related to the spot on.

No this is not normal. The diarrhea may or may not be related to the spot on treatment, however it could be caused by an infection. You really need to take your kitten to a veterinarian ASAP for an exam and treatment.
