Some will adapt better than others, which is why you should start this work at a young age. Any animal or child will tire of certain toys, while others will be cherished and carried around, slept with, or be looked for if removed. Specific bird toys are important for older birds and come in a wide variety of colors, shapes, and materials. Cats need toys that will keep them active and interested. Most of my client favorites are the scratch posts with the spring and a new toy attached periodically.
Dogs have a wide variety of toys they like.
Many animals are never taken into new environments or into a house because they do not behave or act skittish. This is primarily due to lack of socialization or because the level of distraction is too high for them to handle. Social classes or trips to see friends are great. Social trips to the pet professionals are a good idea too, if you have their consent first. Treats and a pat from the Veterinary Staff, Groomers, and Walkers or Day Care Personnel before you leave an animal with them for professional work, will make the whole thing a pleasure and help your pet settle in and not be so traumatized when they go in for services.
