Bald spots?

My Russian Blue/Maine Coon suddenly developed bald spots on his head after we were away for less than two days. Our daughter came over, fed and watered him and played with him morning and night while we were gone and so he was not alone 24/7 and he was raised with her as well. He is 13 and has been healthy other than a heart issue which he is on Lasix for and has tolerated it well. He has otherwise been healthy, but does not tolerate turkey or fish (who woulda thought...fish!) so he eats chicken and beef based diets. We did get new furniture with fabric guard furniture protection several weeks ago, but had not noted him rubbing against it. He occasionally sleeps in one of the chairs, but has no similar fur loss from legs, paws, ets so we kind of have ruled that out.

The spots started out small er, so we took him to the vet last weekend and the vet had no idea what it is. Said it did not appear to be ringworm or a viral infection. No fleas or mites and thought it could simply be a bacterial issue or stress. Gave us anti-bacterial/anti-microbial topical pads to wipe on the spots twice a day four days ago. Spots now starting to look larger and more red. No other areas seem to be losing hair; only head hair seems to be coming off in small clumps.  Guess this will be another $120 . visit to the vet unless one of you kind cat lovers has been through this before and has some guidance. Thanks so much

As an update, it appears that Montgomery's hair is slowly starting to grow in. I say appears since it takes a magnifying glass to see the tiny hairs, but to me it seems they are there. We stopped using the topical wipes the vet dispensed as they were making his spots look red and irritated. After stopping his scalp looked white and the rednssd subsided so I hope we are on the right track. No soreness and he likes to have his head massaged. In totality, I think it was stress overall. We'll see.

hoping with ya...

Montgomery's hair appears to be growing back slowly. Tiny fire hairs at first over the pure white scalp, now all appears a light gray as the hair slowly thickens and the spots are covered with the fine gray hair of her Russian Blue heritage.

We still think it was the stress of us leaving for the overnight trip, along with the new living room set. Montgomery is so much a "person" cat that we're not anywhere sure he even knows he is a cat. He talks back when spoken to and is more human than some people I know

So, we hope the crisis is averted. He is doing fine on his Lasix and has not had any further issues from the congesytive heart problems. We did not keep him on the Plavix as he could not keep food down afterwards. He has lost weight but the vet seems to think that is fine since at 19 pounds he is in the range for a Russian Blue/Maine Coon mix.

I am just glad to have my snuggle buddy back and see him with his head on my pillow at night. Between him and my wife I feel like a hamburger patty!

Best wishes for a winderful and safe Holiday Season to all.

Pardon my typing. It should be "FINE" not FIRE hair. As far as having him back, we didn't lose him anywhere but he was a bit distant for awhile after his vet visit, but back to his old self now, going crazy with the catnip and his scratching toys...and the new furniture if not caught!

Just another update...Montgomery's bald spots are about 90 percent covered now. He still has a small "U" shaped area on his head that is quickly filling with fur. Once again, the vet has absolutely no clue other than stress or separation anxiety. I wish I could blame the loss of MY hair on that but mine just started to disappear somewhre in my middle age and never came back. Oh to be a cat in this house with the life and care. Pate' anyone?
