YES! Max
is 4 months also and he normally does pretty good when we go to the vet or Petsmart
which is 10 minutes from my house, BUT the first 1hr long trip, he threw up 4 times
...the only thing I think may make a difference is because he was so small, I could hold him in my lap while I drive and he was fine, now he is almost too big...the hour long trip he was in the back seat by himself...
so, I would either try to hold him while i drive or just use plenty of blankets or towels and see how he holds up.
