I may be breaking some rules doing this but I am hoping someone can help. My sister in law inhereted 2 orange tabbies and she already owned one, and (2 other felines) she moved into her parents house were these cats lived. In March she did a few renos to the basement area, and her cat showed signs of itching, a few weeks later, vet treated as allergies. Then one of the inherited cats startd itching. Vet did tests and says allergies, now cats are on prednisolone, also have a sister in law that lives 2 hours away and her orange tabby (has 2 other cats also) is showing signs also. her vet says allergies. we have changed foods, cat litter with no improvement. Researched and fungal issues came up as possibility, any help or suggestions greatly appreciated. PLEASE and Thanks in advance.
