Cats can seem self-sufficient and tend to mask their pain, they don't get as much veterinary care as dogs - about half as much in fact - even though cats also need regular preventative care at all ages.
For many pet owners, these instances are merely another part of accepting an animal into their lives. After all, when we offer a forever home, we implicitly agree to take the bad with the good, the hisses with the kisses.
Our pets can't tell us when they're in pain - we have to notice the signs. But often animals instinctively mask injury and illness to protect themselves from predators, so it can be challenging to detect when they're in pain.
