The Question
“Dear Dr. Paola,
We’ve been caring for a feral cat (Oscar) for several years. He’s gotten friendly only with us for the past year. We noticed thin areas on his fur, mostly on the sides near the spine. We thought it was from him rubbing along brick steps. We’ve observed him using his teeth to pull fur out after grooming the area. We don’t think there is any fungus or mites that is causing this as he doesn’t bother the area once the fur is pulled out. Could he have anxiety? What can be done about it if he does have that? Thank you” – Susie
Quick Info about Oscar
Hi Susie, it’s heartwarming to hear how much care you’ve given to Oscar. Ferals are wild creatures and don’t often get friendly to humans, congratulations on winning him over. You are likely to be the only ones of our species he learned to not run away from. Congratulations on your patience and persistence.
The fur thinning and pulling you’ve noticed could be stress-related, but it’s important to rule out other causes, such as allergies, skin irritations, or pain from underlying issues like arthritis. Cats often overgroom as a way to cope with discomfort, whether physical or emotional.
If anxiety is the cause, environmental factors like a consistent routine, safe spaces, and calming pheromone diffusers (e.g., Feliway) which you would have to put as a collar could help, although it will likely be a challenge to put and monitor. I am assuming you are feeding him so ensuring he’s on a high-quality diet with omega-3 fatty acids may also support his skin health. A vet visit would be key to rule out other medical concerns and explore options like supplements or anxiety medication if needed. However, that would involve a transport box. Your attentive care is making a real difference for him!
Sincerely,
Dr. Paola
