I breed persians and have 3 dogs. Once you start buying the food and all you don't really notice the expense in my opinion. The initial cost of getting a dog/cat is not going to continue as the dog/cat gets older. The spay/neuter and vaccinations are the most expensive with the exception of emergency or other health concerns. You can have unplanned vet expenses for health issues or emergencies. All in all I love have my cats and dogs around no matter the cost.
