Hello Marion, I'm Dr. Deb.
I recently came online and see that your question about Teddy hasn't been answered. I'm so sorry that you've had to wait for a response, but if you still need assistance, I'd like to help if I can.
It sounds like Teddy has an Upper Respiratory Infection (URI) or the Feline Flu. This is going to be the most common cause of eye issues and sneezing in a kitten this age.
These infections are usually secondary to viruses (herpes or calici) although secondary bacterial infections can also be seen. When this happens, the discharge (from either the eyes or nose) is usually green or yellow in color and I usually dispense oral antibiotics; if the discharge is clear, then I typically don't.
Symptoms can be seen for 10-14 days although some cats can display intermittent symptoms their entire lives if a herpes virus is involved.
There are several treatment options which may help improve his symptoms:
1. Continue to gently clean the eyes and nose of any discharge. I don't typically advise boiled cooled water but it's fine if you want to continue to do so.
Over the counter artificial tears can be used to flush out the eyes.
2. Nasal decongestant drops can be helpful although many cats don’t like them very much as you can imagine. They should only be used for three days in a row, with one drop in each nostril; otherwise what’s known as a rebound effect may occur
a. Pediatric otrivin=0.05% xylometazoline
b. “Little Noses" Decongestant Nose Drops with phenylephrine hydrochloride
c. Afrin (oxymetazoline)
d. "Little Noses" Saline Spray/Drops non medicated which can be used more than three days in a row.
3. You can place him in a bathroom with hot water running so that the steam can loosen up secretions or use a humidifier can also be helpful if you have one.
4. There are no safe over the counter cold remedies that we might take but antihistamines can help some cats:
Benadryl at a dose of 1/4 of a 25 mg tablet given twice daily or
Chlorpheniramine at a dose of 1 mgtwice a day or
Claritin at a dose of 2.5 mg twice or
Zyrtec 2.5 mg once or twice a day
It is important to ensure that the formulations used contain ONLY the antihistamine and are not combination products (e.g. Claritin-D contains pseudoephedrine, which could cause very significant adverse effects in a cats.
Sedation is a common side effect with these kinds of drugs.
I probably wouldn't use one of these drugs just yet but wanted to include the option so you'd know what was safe.
5. L-lysine can help with any eye issues. Herpes viruses can settle in the eyes and cause symptoms that you're seeing. This product is available on the internet or at many pet or grain stores.
Most cats tolerate this supplement very well but side effects which might be seen include vomiting, diarrhea, and facial swelling/itching (an anaphylactic reaction).
Encourage Teddy to drink by feeding either smelly canned foods or by offering tuna or clam juice.
I hope this helps and that he's feeling better soon. Again, my apologies for the delayed reply. Deb
