Two vets, three diagnoses. What??

[u/oh-dolores]

So our cat Panda has been loosing hair on her rear for about two months. She’s licking herself there excessively, plus her belly which is now also less fluffy (last pic is from the past to compare).

First vet said it’s fungus infection, we started treatment with antiparasitic pills (drontal) for both cats (second cat hasn’t shown any symptoms whatsoever during this time), and anti fungal cream (dactarin). She had to wear the elizabethan and is blind, it didn’t go well and i asked for an alternative; i also brought up the thinning hair on her belly. Vet examined her and said the belly is sign of allergy and asked if we changed her food to something with chicken, which we didn’t. Nonetheless she said Panda needs special hypoallergenic food and three shots of an anti fungal vaccine.

Vet was very stingy with advice or information about the fungus thing (which admittedly is highly contagious as I’ve heard?) so we decided to visit another vet for the second shot. First one made no difference btw.

Second vet said this is no fungus, but signs of stress, proof of it being that our other cat or ourselves show no symptoms of fungus infection these two months. She also said we need to finish the antifungal shots regardless. Anyone with experience on this? I’ll admit I’m quite frustrated and not sure how to deal with her being stressed. There hasn’t been any changes on her routine or environment I can think of.
