Q. I just adopted 2 kittens 4 months old. They we're given doxycycline 100mg b/c they had upper respiratory.its been 4 days. They are still sneezing.
A. It can take longer for all the symptoms to clear up. If there are signs of some improvements then that's good. If not or they seem worse then go back to your vet as another medication may need to be added. If there are improvements then keep going as you are. If you get towards the end if the course of medicine (a day or two from the end) and they are still showing symptoms then speak with your vet as they may wish to extend the course.
