Do animals love? First, love means something different to everyone, making it hard to define. Second, there are many types of love, including the kind between parents and children, among siblings, and with couples. But the biggest problem is that animals can't tell us how they feel, and scientists can't set up experiments to find out. All we have to go by is our interpre­tation of an animal's facial expressions, vocalizations, body language, and behavior. Two stray cats were always together. Not only that, one led the other wherever they went, with their tails entwined. How come? Unable to get close to them because they were so wild, a woman who looked after stray cats trapped the pair. That's when it was discovered that one cat was blind. A cloudy film covered his eyes. His sighted brother acted as his guide, hanging onto his tail and always stepping a bit ahead.
