One day I woke up and my cat had a bald spot. Naturally I panicked and went to google and cried. She had red patches and she kept licking herself aggressively to the point she had a bald spot. I do not know what happened. Before new years she was fine, and after new years this happened. I do not know what happened. She just stays in my room so I'm sure she didn't have fleas or any parasites. After looking at Google for a long time I thought she had either dust mites or dermatitis. It's really dusty in my room, I sweep like 2x a week but maybe that wasn't enough? She never had a bath in over a year so, maybe she was dirty? But from what I've read online, I had to buy her this shampoo to help kill the bacteria, some salmon oil to improve her skin health and immune system, this ketowell spray, and cocunut oil.What I did to get rid of her red patches & bumps is to first wash her cat bed and blanket in the washer & dryer. I hand cleaned her toys and cat tree. I cut her hair around her bald spot and tail. Gave her a bath every week for about 2 months. Used the ketowell spray for the first week every day (***make sure it dries completely before u let ur cat out of ur sight***). Then I used that spray every few days. It helped calm her itchiness and stop her licking her skin as much. Then I integrated that salmon oil in her food, I bought her canned food since she was sick lol. I only put a little bit the first day, skipped the second and continued. Gradually increasing the amount. So far I only put half a teaspoon in her food every day now. This was in January so it's been 4 months since then. Every time I gave her a bath I put the cocunut oil on her exposed skin & paw pads. I brushed her everyday. I swept the floor every day including where her cat litter is. I mopped the floor every week. I removed the top of her litter box, she had one that is fully enclosed with a door but, I decided the take the top off because I don't know if that is what caused the bumps or not either.So after my routine I noticed her bumps formed to red patches, and from red to orange, to flakes, to finally nothing being there at all. Now her fur grew back. And she's all better. No bald spot, no bumps, no itchiness. It took about one month for her to get better.I cannot say what worked. Was it the shampoo? The ketowell spray? The salmon oil? Me cleaning all her belongings? Maybe it was all of it combined. But I'm happy to say my baby is okay.Nowadays I just put salmon oil in her food every other day, I brush her when I notice there's lots of hair when I pet her, I give her a bath with this shampoo when she's starting to feel grimey, and I clean her blanket when I clean my blankets too.All in all, I'm not sure what really got rid of her bumps/red patches but I'm not complaining. I'm just happy she is okay now & she is still okay. No sign of them coming back. Whenever you're petting ur pet make sure you inspect them! It was scary just waking up one day seeing a bald spot and red bumps on my baby. I hope this review helps if you're experiencing the same thing.
