Animals are intrinsically worthy of rights because they are sentient  Sentience is the property of being conscious. Sentience brings with it the ability to experience. There is a massive difference in the way that we treat sentient and non-sentient beings instinctively. We see nothing wrong with forming relationships with one’s pets but we tend to deem people with emotional relationships to objects mentally ill. Here we are talking about something more than sentimentality but rather the kind of relationship in which one is concerned with the other party’s emotional wellbeing. We even feel concerned about the wellbeing of sentient beings which whom we do not have a personal connection. For example we may feel upset when we see a dog run over on the road. This would be a very difficult reaction to how we might feel if we see an object crushed by a car. We feel moral outrage at the clubbing of seals.  The instinctive way which we differentiate between these two categories relates to the type of value they have. Whilst objects have value because of how they affect us - e.g. they are useful or remind us of a good time or person – we believe that animals have intrinsic value.  This means that a sentient being must never be treated as a means rather than an end in and of itself. Animals are sentient. Therefore, animals must not be treated as a means to an end but as intrinsically valuable.
