Has anyone seen these strange lines and bumps on a cat’s skin before?
I adopted a 6-month-old male cat who looks like a Devon Rex. When I got him, he had a long vertical line on his belly that looked like an old healing scratch, plus a few smaller similar lines under his armpits and some large pimple-like bumps on his head.
About 3 weeks later, his skin got much worse. He developed:
- More large bumps/pimples on his head and back
- A rash across his body
- More of these strange lines on his belly and under his armpits
- The original long line on his belly split into two and became dry
I took him to the vet. His bloodwork was normal, but skin testing found ringworm in some areas and a bacterial infection in others.
He was prescribed:
- Oral antifungal medication
- Medicated shampoo
- Antibiotics for 1 week
- Allergy medication because the vet suspects the rash may be allergy-related
He has been on the allergy medication for 2 weeks. The rash has improved, but the lines aren’t getting better, the large bumps on his head are still there, and new random pimples keep appearing on his back.
He’s now on his second round of oral antifungal medication (1 week on, 1 week off, then another round).
The vets I’ve seen aren’t sure what the lines are and think they may be related to allergies.
Has anyone seen lines like this on a cat before? Any idea what they could be or what I should ask my vet to check next? thank you in advance <3
