felecia187 this may be stupid but it is so true you never see obesity in wild animals ever see a an obese bob cat that weights OH say one thousand pounds nope but you can see a house cat that weights forty pounds because the owner is over feeding the cat , some house cats need to be given one dish of food a day and some you can give lots to and they will only eat what they need kind of like people you fill one persons dish and they eat everything on it you fill the other persons dish and they eat what they need , now when you find animals in the wild that may appear to be obese you find that the extra weight they carry helps them to survive in cold water or cold places , but people don't have to be fat to survive in cold places so the next time you go to the zoo check it out the kids will love it , enjoy
