I see you're right, that civets are not felines. Here is at least one viral disease that infects both, however: Feline Panleukopenia .

From this link:

Viverrids such as the civet are susceptible to canine distemper, feline panleucopaenia, and rabies. These animals should be included in a vaccination schedule as above. Other diseases to which they may succumb are similar to those of canids and felids, and should be handled accordingly.

I wonder if they get FIP.
