Texas is a yearly rabies vaccine state, as is my county. Considering that my dogs don't stay home, 24/7, I will be forced to give that vaccine at the least. And yes, we see cases in Texas of rabies every year, some years being worse than others.
As to the other vaccinations, I've never heard of having titers done until I started researching (and reading about it on the boards). I'll ask my vet about that and see if that's something they perform (they're a little ... old school). Otherwise, I may have to find a more progressive clinic to go to, but I don't want to as I like the two vets there and they are quite empathetic with the animals. The older vet is a bit less so with cats, though. The younger vet is good with both and both seem to realize that pets are valued family members, without being pushy about treatments. They give you options and also don't try to make you feel bad if you want to try something conservative (and less costly) first.
