Answer 1

Your dog or cat will need lots of fluids, and sometimes humidifiers can be helpful with the coughing and congestion. Really, anything you would do for yourself if you had a cold would probably help.

Answer 2

you need to take your pet to the vet. they will prescribe antibiotics and possibly a decongestant.

Answer 3

I would take my cat in to get treated by her vet. It might be the start of something else, and it's better to be safe than sorry.

Answer 4

the vet can't really do anything, unless it's more than a cold, like if it's an infection or pneumonia. just make sure he or she gets lots of fluids and is eating alright. keep an eye out in case it lasts for a couple weeks and then take him or her in.
