Do not buy friends, take a pet in a shelter!
Contact the curator of the animal and in detail ask about his character, habits and problems. Try to get as much information as you can about the pet.
Discuss with your family your intention to shelter your pet and get their approval. If you are renting an apartment, be sure to notify the landlord.
Take care in advance of buying feed and accessories for keeping animals such as a tray, a carrier and a scratching post for cats, and for dogs a collar, muzzle, etc.
Be sure to take your pet to the veterinarian, check his health, take basic tests.
Be patient. It takes different time for different animals to adapt to a new place and for life outside the shelter, try to be more lenient with the pet's mistakes, while at the same time making it clear who is the boss.
Be careful! Very often, animals taken from a shelter when they are out of a cage or an aviary lose their heads and run away. Keep them on a leash for the first time until they get used.
Surround your pet with attention and a positive atmosphere, try to give him as much time as possible.
Give your pet love and care, he will not be indebted!
