Causes. Headaches can be triggered by a variety of factors. The most common cause of headaches is prolonged tension or stress. These are called tension headaches or muscle-contraction headaches. Virtually everyone suffers from this at some time. Muscles in your scalp, neck, and face tighten and contract, causing spasms and pain.
Cat milk alternatives: If you want to give your cat milk, the safest bet is to purchase special lactose-free cat milk from your supermarket or pet store. Bear in mind that milk contains calories (water has none) so do keep it minimal. Obesity has serious health implications for cats.
Causes of Lactose Intolerance. When adult cats eat milk or cheese, many of them will develop lactose intolerance symptoms such as gas, bloat, abdominal pain, and loose bowel movements. The reason that most cats experience these symptoms when they eat dairy products is that their digestive symptoms are not designed to handle these types of foods.
