My cat has been diagnosed with an allergy to house dust mites. He is wearing a buster collar and another collar I made myself to stop him from scratching the back of his neck. If I take the collars off he scratches the very same spot and is making it bleed. A viscious circle because then I have to leave the collars on till it heals, The steroid he got 2 weeks ago is not helping it. I am now waiting for a vaccination which we shoul have this week. But it could take 8-12 months for this to work, if it works at all. In the meantime the poor cat is wearing the collars and has to stay in as I cannot risk further injury with the area he is scratching. Has anyone else experienced a problem like this with their cat?
