Cosmo is a 3 yrs old Male cat. Recently he began to scratch his ear and neck until all is bloody and raw looking. Also these places have lost fur. He is in pain. I gave him Benadryl tonight and is sleeping well. What products or home remedy can I use as his vet is an hour away and we have snowy conditions

Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely due to allergies. Benadryl is good as is prednisolone for example. However, these are only going to help with the itch temporarily. However, it is crucial to get rid of the allergic component and treat the allergy as if not, the itch will continue. Also, it is crucial to treat the likely secondary infection. There is no at home treatments as the other medication that can be used in cats for this is a prescription medication called prednisolone. One thing you can do at home besides dealing with the possible allergies is using an e-collar which you can get from your local pet store or online to prevent any further self-trauma. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!
