PHP - How to catch a 'Trying to get property of non-object' error

I am trying to catch 'Trying to get property of non-object' error with a try/catch statement but it is failing, I still get a PHP error. I am using as:

try{
  $id = Model()->find('id=1')->id;
}catch(Exception $e){
  echo 'failed';
}

My find function returns an object (Active Record) and I can access the id column as shown via object prop.

However, it will be null object if AR is not found. I thought the try statement would catch this. A work around for myself would be to use an isset(). But I am confused as to why the try statement does not accept and catch this error.
