It is safe to give your cat Afrin Children’s Strength Nose Drops. You’ll give him one drop in one nostril one day and one drop in the other nostril the next day. Continue the process for five to seven days.
You might even give your cat a heating pad while he is ill. Ensure the heating pad is on its lowest setting and that it is covered with a towel. Also be sure your cat can get off the heating pad if he gets too warm.
You might also try offering her chicken broth. The broth can be warmed in the microwave to bring out its aroma.
Humidification of the nasal passages may also help your cat, you can do this by purchasing a humidifier for the room or bringing your kitty in with you for a nice steaming in the bathroom.
Run a soft towel or sponge under warm water and gently wipe away any discharge from your pet's face.
The best thing you can do for now, is help your cat decongest a little by running a humidifier in your home, or in the room he spends most time in, and also run a hot shower to steam up your bathroom and sit in there with him for 15 minutes at a time, every few hours. Make sure he doesn't get a chill upon coming out, and wrap him in a towel, if he'll allow.
One thing you can try is a l-lysine supplement. Most cat colds are caused by either the calici virus or the feline herpes virus. L-lysine is very helpful at battling the herpes virus. Lots of fluids is something my vet always recommends for a cold too.
You should be able to purchase the l-lysine at a pharmacy or health food store. I've seen discussions on here about making sure they don't have added ingredients that aren't good for cats. I'm not sure what those added ingredients are (since we buy one made for cats), but read the labels and if there are added ingredients you could google them or ask your vet. I know there are plenty of folks who use the one sold for humans.

L-lysine capsules can be easily found at health food stores and at Wal Mart in tablet form. Wherever you buy it, read the label. Do not purchase any product which contains any "glycol" ingredient, which is toxic to cats. Dosage is 250 to 500 mg per day for kittens, and 500 to 1,000 mg for adults.
If the URI symptoms are severe enough to cause your cat to refuse food due to mucus buildup in the sinuses, a single drop of Afrin Children's Strength Nose Drops (.025 percent Oxymetazoline hydrochloride) can be administered to one nostril per day, but use it no longer than five days in a row, switching nostrils for each drop.
