With patience and understanding you can teach any old dog new tricks, depending on what you are trying to teach, or un-teach the dog, which is usually more difficult. Dogs can learn at any age, and like humans, it’s just old habits that are hard to break! A cat will almost never meow at another cat. Cats use this sound for humans.

Cats, unlike dogs, do not learn tricks to win your approval. Cats can be taught to perform tasks such as retrieving toys and jumping through hoops – but it may take patience and perseverance…and quite a few yummy treats for your feline. Source: Animal Leaque
