I suggest that Razor just do not understand what is text and what has to be value in your drop down list options so it just generates empty drop down (no value attribute). U can check your rendered html, I suppose it looks like 

<select>
   <option>Category1Name</option>
   <option>Category2Name</option>
   <option>Category3Name</option>
   ...
</select>

U should use IEnumerable<SelectListItem> as a source for your drop down. Example:

[HttpGet]
public ActionResult AddProduct()
{
    // this has to be the list of all categories you want to chose from
    // I'm not shure that _cat.GetCategory() method gets all categories. If it does You
    // should rename it for more readability to GetCategories() for example
    var listOfCategories = _cat.GetCategory();

    ViewBag.ListOfCategories = listOfCategories.Select(c => new SelectListItem {
        Text = c.CategoryName,
        Value = c.CategoryId
    }).ToList();

    return View();
}
