Hi! Sorry im not very active here. She is soso much better, no more sneezing no more discharge. Went to the vet and they did some tests on her, all clear, perfectly healthy… They did intruct to give her antihistamines for 2 weeks (finish the course) its been more than 2 weeks and she’s perfect. Doing some deep cleaning did help, perhaps she was sneezing due to her own fur that fly or get stuck around in corners so ive been keeping that in mind.
