I am fostering a 3 week old kitten with a URI. Today is day 4 of her antibiotics doxycycline and I'm not seeing much improvement. After how many days should I consider switching antibiotics? Also is it more important for her to sleep during this time or should I encourage some activity? How often should I use the humidifier? How important is handling her to her health improving?

You are doing everything in your power at the moment, i can't think of anything else you can do. due to him getting worse it might be a good idea to add some bronchodilatator meds to his antibiotics, you will need to get that from your vet. oxygen therapy is also an option if he seems really lethargic. usually improvement is seen within 3-4 days from the start of the antibiotic course.

That sounds a bit concerning... If she is eating and drinking and acting pretty normal I guess I would give a few days for the antibiotics to kick in.
If she is not eating or acting normally (like this breathing pattern is new) then you should get her back tot he vet for a follow-up. X-rays may be needed to check for pneumonia or a diaphragmatic hernia.
You know her best so if you are worried go with your gut instinct.
