The vet my cats get their routine care at has switched to suggesting intranasal for most routine vaccines in cats. The evidence seems to be that intranasal conveys a slightly better immunity (possibly by specifically sensitizing the mucous membranes) and avoids the small but well-characterized injection-site sarcoma risk, at the cost of a 30% chance of some minor cold-like side effects for a few days.

Is this available for the rabies vaccine too, or just for FVRCP?

I don't think there is an intranasal feline rabies vaccine available, but the booster schedule is now out to 3 years.
