Jason, thanks for answering the questions!! You seem like a pretty responsible person. However, could you answer these questions more specifically?
How much time do I have to clean up after a pet every day? [puppies and kittens make lots of mess! Certain breeds do, too!]
How much money can I spend on veterinary care every year? [for three dogs, my family spends $4,000 to $5,000 a year. The cost of veterinary care is usually based on the supplies used and time spent. Veterinary care for your chihuahua can and probably will cost as much as veterinary care for your friend's great dane]
How much money can I spend on general supplies (toys, leashes and collars, etc.) every few months? [puppies and kittens need lots of toys to play with. Collars and identification tags are important for boths cats and dogs, and dogs should be exercised daily]
How much money can I spend on food every month? [it can cost often over $50]
I suggest you check out your local shelter and search
