Each species evolved over millions of years to become what it is today, the

food they eat, their social behaviour and physical needs are all based on this. Domestication is a very short part of evolutionary history, so many of the demands of domestication such as diet, how we ask our animals to live, and our alien social customs, can cause mental or physical stress.
Many problems, including itching skin, bad breath and m unwanted behaviours arise because domestic animals eat an unsuitable diet, high in fats and sugars, preservatives and other additives, or low in trace nutrients.
Our animals also live in an environment which causes them psychological and physical stress; for instance lack of company, exercise or clear rules all contribute to stress levels and chronic stress leads to ill-health.
I do not say we should free all animals and send them back out to the wild to fend for themselves, but I do think we should try and provide them with what they naturally need as far as it is possible in our individual circumstances.
There are many simple ways animal guardians can change how they manage their animals to increase health and well-being. Find out how in our articles section.
APA educates and advises owners how they can provide an 'as natural' lifestyle for their pets, even if they are living in a city apartment, thereby reducing many of the stresses which are the cause of illness and behaviour problems.
