Of course, it's important to know how to care for animals. It's important to know how to feed them properly (otherwise they will become ill), it's important to get them to see doctors and so on. But still, you can know all these rules, but it won't help. You know why? Because it's the most important thing - to love your pet. It's important to give them your love all the time, so they could feel it. Love can heal many things.
However, it's important to remember that providing love does not always mean providing treats. Oftentimes, when one feels as if their pet is being neglected, it's easy to offer some tasty things to compensate for the lack of love. But don't forget that the number of obese pets is growing as fast as the number of obese people - certainly you know the danger of such process for a human. So try to remember that the danger for a pet is absolutely the same - it harms its health.
So before you decide to buy a Sphynx cat, ask yourself a question - will you be able to take care of it, provide it with the love it needs and be his best friend? If you can answer yes to all the questions, then you'll be a good owner.
Never forget that it's a great responsibility to have a pet.
