 If you've seen YouTube videos of cats getting brain freeze while eating ice cream, you might be tempted to give your cat a spoonful or two. Unfortunately, all that milk and sugar could cause more than just a brain freeze. If you've ever googled can cats eat ice cream? You might see conflicting points of view. While humans are entitled to their opinions, reality has to be backed up by scientific facts. According to experts, research studies prove that most cats are lactose intolerant. This means that giving them ice cream is a bad idea. To put it simply, cats have difficulty digesting dairy products including foods made with cream such as whipped cream, milk, cheese, and butter.
