Sneezy congested cat
Baci (4 year old male neutered sphynx cat) has been going through sneezing fits lately. 2-3 times a day he will sneeze 15-20 times in a row. At night he also sounds congested but not in the day. This has been going on for about 5 days.
There's no goopy stuff from eyes or nose and his behaviour is 100% normal (except for the sneezing and night congestion) so I'm not extremely concerned...
Should I be concerned?
