When you get a new cat, whether from an adoption agency or a friend, there are preparations that need to be made to ensure the new addition's smooth integration into your family. Here are some things you should do when you get a new cat.

First, provide your new cat with a proper diet. Cats of different ages and breeds need different diets. Consult a veterinarian or professional to find out what kind of diet your cat needs and provide it with quality cat food. At the same time, make sure it has enough water to keep the body healthy and hydrated.

Next, give your new cat some time to adjust to the new environment. Cats are very sensitive animals and can be nervous and upset about new environments and new owners. So give it some time to adjust to the new family and routine. Don't force it to be close to you, but give it enough space and time to adapt. 

In addition, take your new cat to the vet. Whether you're getting a new cat from an adoption agency or a friend, you should take it to the vet for a full health check up. A vet will check his health, vaccinate him, deworm him and take the necessary precautions. This will ensure that your new cat is healthy and prevent any potential health problems.

Finally, give your new cat plenty of love and attention. Cats are very independent animals, but they also need the love and companionship of their owners. Spend time interacting with it and giving it love and attention. This helps build trust and intimacy between you.

All in all, when you get a new cat, there are a few things you need to do to make sure it fits smoothly into your family. Provide it with a comfortable home, let it adapt to its new environment and take it to the vet. With these measures, your new cat will be able to quickly adapt to the new environment and build a wonderful relationship with you.
