Hello. Thank you for asking your question. My name isXXXXX will try to help.

I would keep him away from your house cat, until you know what the cause is. You can keep him locked in a bathroom or small room.

Upper respiratory tract infection would be the contagious one. Signs are sneezing and nasal drainage. In addition, they can also have coughing.

To help with the nasal symptoms, you can put a drop of nasal saline, in each nostril, twice a day. This helps flush out mucous and helps with inflammation.

You can also give him the human antihistamine "chlorpheniramine." It comes in 4 mg tablets. Give 1/4 tablet twice a day to help with nasal symptoms.

Offer him low sodium chicken broth, cream, tuna juice, or clam juice mixed with water to help keep his hydration up.

To help with dehydration, you can also give him children's pedialyte drink with a syringe.

You can put a little pancake syrup, in his mouth every few hours, to keep his blood sugar up if he is not eating.

When you take a shower, take him into the bathroom and steam out his respiratory tract.

You can feed him canned food, or human meat flavored baby food (without onions or garlic) warmed in the microwave. Warming it makes it more fragrant. They will not eat if they have nasal congestion and can not smell their food.

If he is just coughing, and wheezing, and not having any nasal symptoms, then it makes upper respiratory less common.

That is more likely asthma, heart disease, or a foreign body stuck in his throat.

Just to be on the safe side, keep the cats separated until you have Scooter diagnosed by a veterinarian.

Wash your hands, after treating Scooter, to prevent the spread of germs.

If your house cat has already been exposed, it is not the end of the world. Hopeyfully she is vaccinated against the common respiratory viruses and if she did get sick, she could be treated as well.

I hope this helps.
