There is a ring in the Cash Shop in Pet Society that makes your pet disappear. If you put clothes on your pet and then the ring you will have no head!! The ring is $10 real money, unfortunately.
You need 0% hygiene and it needs to be 100% full, try to keep it as happy as you can. You might want to put some extra food on the ground for when it gets hungry your pet can just pick it up and eat...
Well you don't but your facebook friends will be on there but you cant talk to them unless your on chat you can add some pet society fans to be in your friends as well if you liked.
You can get a petling in the Outdoor store/Petlings. There are different varietys of pets. The kitten is 1,000 coins. The puppy is 1,500 coins.(<I'm not too sure) Other petlings are either...
