User Story

I have added surcharges for my services based on the gender of the pet. For example, cleaning the sanitary areas of pets differ between male and females, or even between female and spayed females. Male pets can be more aggressive than neutered males or females. For that reason, I would like to classify pets by gender.

Most of my client’s pets fall into the genders:

Female

Female – spayed

Male

Male – neutered

I’m thinking of expanding into large animals, so for horses, I would have to add Gelding and Rig.

For that reason, Pet Gender has to have some flexibility!

User Story

I charge for my services based on species and breed. For example, I groom both cats and dogs. To bath and brush a cat is more work than bathing and brushing a small dog. Cats won’t sit on command! Different breeds of a species require a different about of work. For example, a groom of a beagle entails a bath and brush whereas a groom of a poodle entails a bath, brush and hair cut. I would like to categorize by clients pets by species and then breed.
