Mongoose: series of custom instances

According to the documentation I can do such thing:

var animalSchema = new Schema({ name: String, type: String });

animalSchema.methods.findSimilarTypes = function (cb) {
  return this.model('Animal').find({ type: this.type }, cb);
}

Suppose I have another function:

animalSchema.methods.owner which filter if animalScheme.owner is xyz, so it modifies the search query to {..., owner: xyz}

Is it possible to use instance sequentially? and how can I achieve this?

var animalSchema.findSimilarTypes().owner("xyz") ?

any hint?
