Create a Entity-Relationship Diagram (ERD) using standard ERD notation for cardinalities for the following information:

A pet has a name, an owner, a species, a sex, a birth date, and a death date:

name	owner	species	sex	birth	death

Claws	Gwen	cat	m	1994-03-17
Buffy	Harold	dog	f	1989-05-13
Fang	Benny	dog	m	1990-08-27
Bowser	Diane	dog	m	1979-08-31	1995-07-29
Chirpy	Gwen	bird	f	1998-09-11
Whistler	Gwen	bird		1997-12-09
Slim	Benny	snake	m	1996-04-29

An event in the pets life is something that happens to the pet. An event has the pet to which it happened, a date, a type, and a remark:

A vet is a person, and has a name, an address, and a phone number. For the purposes of this exercise, assume all vets work as sole practitioners; we dont have partnerships here. Its possible a pet will have no veterinarian (it may be very young). Its also possible a pet will have more than one veterinarian.

Assume that the vet is not related to an event. A vet may only (possibly) be related to a pet in that the pet could be the client of a particular vet. Events are completely independent of veterinarians.
