Dogs and cats are sociable animals when it comes to humans, and need your attention. Don’t think that having more than one pet will be enough to replace you. Also, not all dogs and cats like other animals, so getting a ‘friend’ for your dog or cat could make matters worse. Some do cope better than others being on their own for extended periods but this very much depends on what they have been taught at a very young age. If a dog or cat has been taught to cope being alone before six weeks of age by the breeder, they tolerate isolation better than pets who haven’t been left alone at all.
