Cat pulling out fur on tail and lower back

Hi everyone,

For over a year now, I’ve been trying to understand what’s going on with my cat, Murphy. He’s a 4-year-old male I found on the street when he was only six weeks old. Since then, he’s been neutered, vaccinated, and wormed. He’s an indoor cat, living in a large flat with his adopted sister, a female cat I also found as a stray two years ago. Murphy is usually a calm, curious boy—not much of a player, but extremely affectionate and sociable.

Last November (2022), he started showing unusual, agitated behaviour (tearing through the hallways, dilated pupils, excessive meowing, pacing around the flat, being more playful than usual...). Since this didn't stop, I took him to the vet in December, but they didn't find anything wrong. The behaviour eventually settled down but was replaced by hair loss because he started pulling his fur out around his lower back and tail. I should mention that in November 2022, I took in a 6-month-old kitten from the street who was malnourished. I kept the kitten for about two weeks in a separate room; they never had direct contact. The vets I’ve seen all told me there was no link and nothing could have been passed on, but I wanted to mention it just in case.

Since January 2023, I’ve been going to the vet every month to rule things out:

- He didn't respond to steroid injections for allergies.

- He doesn't have fleas and didn't respond to flea treatments.

- He’s been on a strict hypoallergenic diet with no results.

- Ringworm tests came back negative.

- His blood work is perfect; nothing showed up on the X-rays or CT scan (a dark spot was found on his lungs, but a biopsy ruled out a tumour; the theory is it was a reaction to the anaesthesia).

- An osteopath who examined him noticed "rolling skin syndrome" and what she called a desynchronisation of the organs between the head and the lower body.

- Our vet has ruled out behavioural issues because we tried a course of Reconcile (to help calm and settle him), but it didn't change things.

Despite all this, he seems to respond well to pain relief. When he’s on it, he pulls his fur out less, but it’s still not right. I think he’s still in discomfort or pain because for a few months now, he’s been distant and lethargic. He sleeps all day and doesn't seek out my company like he used to, nor that of my other cat, even though they used to be inseparable.

I’m at my wits' end. We’re just going round in circles. My current vet is suggesting laser therapy sessions for the pain, but she hasn't given me any real leads or other theories to explain why this is happening.

I’m thinking about seeing an animal behaviourist and getting in touch with a specialist feline veterinary centre for a second opinion—maybe even starting over with a new vet.

All I want is for Murphy to get better and to have my old cat back—the happy, healthy one. I can't stand seeing him like this, and I’m starting to despair that things will never change.

If any of you have any ideas, have been through something similar, or know someone who has, I’m all ears!

Sorry for the long wall of text...

    Good evening, what you’re describing with Murphy is exactly what I’m going through with Rhéa, a long-haired cat I rescued from some woods three years ago now. She’s been having these episodes for two years. She’ll be calm and then all of a sudden she starts running around like mad, as if something is really bothering her back end; then she stops, her skin starts twitching on her hindquarters, and she pulls out clumps of fur. It had stopped over the winter, but it’s been starting up again since March, to the point that the base of her tail is bare and her hindquarters are full of bald patches. Since Rhéa is still quite feral, it’s difficult for me to take her to my vet. I give her Credelio four times a year for ticks and fleas, but I don’t get the impression it’s doing much. I gave her some four days ago, so we’ll see. I’ll let you know if there’s any improvement. If you find Murphy is listless and not himself on the treatment, stop it. If he was more affectionate and playful before, it’s because he was coping better then. In my opinion, perhaps you might have the possibility of seeing a feline dermatologist. Have a good evening, Muriel

    Thanks for the update, Murphouille! How interesting! And what a surprising diagnosis! It sounds like a behaviourist was the one who figured it out—well done to her! I’m no vet, but I’d never have guessed that. I’ve got a little girl myself who I was told was having focal seizures (based on some videos), but she has "sporadic head tremors", so it's nothing like Murphy’s symptoms. So, I suppose Murphy will be on medication for life? Still, better than the cone, I’d say. Wishing him a long and happy life anyway, and thanks again for sharing the diagnosis; I’m sure it’ll help someone out one day...

    Hi everyone, I just wanted to give you an update on Murphy's diagnosis. After seeing a feline behaviourist vet, she started him on epilepsy treatment. Actually, Murphy once had an episode where he was drooling excessively, and it turns out that can be a sign of a seizure. At the time, the vet thought it was just a reaction to his flea treatment. Murphy has been on his medication for two months now and he's doing much better. We took a break after a month to see our vet, who gave us a new prescription because the treatment was proving effective. During that break, Murphy relapsed and started pulling out loads of his fur again, which confirmed the epilepsy theory for us. I think I'll stop the updates here as we've definitely found the cause of the problem. I hope this helps some of you with your own cats!

    Thanks Murphouille! Happy New Year to you too! And thanks for such a lovely update! I'm so glad to hear that your Murphy is much more settled now. I really hope you’ve finally found a permanent solution! Also, well done on managing the baths! (In my mind, it’s always seemed like an impossible task unless the cat has been used to it since they were a tiny kitten, but I’m probably wrong...). All the best, and I look forward to the next update – hopefully with even more good news!

    Hi everyone and Happy New Year! I’m just checking in with an update on Murphy after three weeks on Zylkene. He’s pulling his fur out much less, although I still catch him doing it from time to time, mostly on his tummy, but it’s pretty minimal. The fur on his tail hasn't grown back yet and it doesn't look great; the skin underneath is almost black. My vet says it's due to excess sebum, so I’m giving him a bath every now and then in the hope it improves. Where I have noticed a real change, though, is in his behaviour. He’s a very cuddly, affectionate cat, but since his fur issues started, he’d been a bit more distant, both with me and my other cats. Since starting the Zylkene, he’s back to being a total sweetheart all the time, rather than just a few days a week. So, I think it’s definitely having a positive effect, even if it hasn’t completely solved the problem just yet. I’m going to finish the 30-day course and I’ll keep you all posted. Also, my vet is meant to be getting back to me this month to discuss his progress and to book some laser sessions for the pain.

    I haven’t got any news to give you about Murphy yet; I only started the treatment yesterday, as I was waiting to finish the course of Neurontin my vet prescribed before starting anything else. The problem is always trying to figure out whether they’re in pain or if it’s a behavioural issue. If there’s no response to the anti-inflammatories, that’s still useful information to give your parents’ vet to help rule things out. Then again, Murphy has reacted better to some pain treatments than others, so it’s hard to draw any firm conclusions. I’ll keep you posted on the Zylkene, and we’ll definitely be trying the laser therapy sessions in early 2024.

    Hi there,

    Have you thought about trying CBD oil? It’s brilliant for stress, really calming and acts as a natural painkiller too. It’s just an idea, but I use it because my cat also had a habit of pulling his fur out and the vet couldn’t find any underlying issues. He’s doing much better now. 

    Here is the link to the pet-safe CBD oil I use: [link to a specialised pet CBD oil]

    Best wishes

    Hi Murphouille, any news? Have you started the Zylkene, and have you noticed any improvement? I’m really worried about my parents' cat. They’ve seen the vet again, who’s prescribed Metacam for two weeks this time, and he’s been on it for a week now! But yesterday I saw him with a clump of fur in his mouth and he got quite aggressive at one point when we were stroking him in that area... He’s still eating that special joint-care dry food and an Omega supplement. He’s 15, and even though he’s not my cat, I’m so concerned, especially about whether he’s still in pain despite the anti-inflammatories. That’s why I was checking in, to see if the Zylkene is having a positive effect on your cat. Thanks in advance.

    Yes, it is strange indeed. My vet tells me it's just one of those cat mysteries and that sometimes, there's no point in looking any further as we'll never find the cause. The main thing is to find something that gives them some relief. That's what I'm trying to do—I've ordered some Zylkene, and I'll make sure to give you an update after the three weeks are up! That said, I'm really struggling to stop searching for the cause; I'm worried it might be something serious that will only come to light in the future, even though now is when I can actually help Murphy... So, I think I'll try to get some other expert opinions, and if I find out anything that might help your cats, I'll be sure to let you know!

    You're right, it'll only help him relax if it works. But it’s still very strange! Just like my parents' cat, only the pain relief actually made a difference, but nothing showed up on the scans for Murphy (my parents' vet told them an X-ray wouldn't necessarily be "useful" even though he’s in pain in that spot... I didn't really understand why, but anyway, he didn't end up having an X-ray or a scan)... Really odd. Let us know how you get on with the Zylkene? My parents have got theirs on a special joint-care diet and an Omega 3 supplement, I think. I'll also let you know if things improve over time... Best of luck.
