You cannot put animals off as if they were second-rate creatures. You can for instance not just throw mildewed slices of bread (or other kinds of "fast food") over the fence to an animal, on a place where it also drops its stools. Endangering the health of animals is an injust limitation of freedom too.
To many animals as well, it matters that being free to come into contact with their congeners belongs to the qualities of life. The same goes for not having to be frightened or for being able to practice skills under natural circumstances, etcetera.

Something similar applies to the quality of lending aid. In Holland f.e. there is no law that organizes the start or management of animal-ambulances, and no demands are made about voluntary aid to animals, with the exception of registered animal asylums or shelters. An asylum cannot take up animals in unlimited numbers. The result is that whoever finds an animal that needs care, starts looking after it himself or herself or organizations that lend assistance - with the best of intentions - accomodate such animals at private homes. This often concerns animals that are "too common" to be brought to an asylum (such as jackdaws, crows, gulls and rabbits). Knowledge about a responsible (re-)introduction of the animal in nature is lacking, and all it is is in fact only putting off the evil hour.

 
Another consequence is that "bunglers" and people who themselves are in need of help, under the cover of "therapy" start to meddle with the sheltering and taking care of sick animals. In fact they pay little attention to the animal, for they themselves are in need of attention. In this way they reduce the animal's chances on healing (and subsequently regaining freedom).

The habitats that are now left to animals living in the wild often are grounds man himself does not want to exploit. The biodiversity of plants in nature decreases by over-fertilizing and environmental pollution. These habitats often only suit animals that make no high demands upon their territory.

Also to be considered are the so called "zero-grazing" pastures, because more and more cows are being kept inside the stables all year long, for economic reasons only. Many people are far from happy with this un-natural development, let alone the cows ....

Furthermore safety measures, such as the ones practiced in traffic, should also be developed for animals in order to prevent animal traffic-victims. Examples are: wildlife-tunnels, wildlife-flyovers or eco-ducts, wildlife wire-fences, etcetera. "It is only an animal" may not be the motive to neglect the interests of animals.
