18. Sphynx Cat
The wide-eyed sphynx cat is a coveted breed that costs $1,500 to $4,500. This strikingly hairless cat will need you to buy a sweater for it since it cannot handle low temperatures.
It has an unusually fast metabolism too, necessitating a high-quality diet of canned and root food that allows the cat to regulate the amount of oil its skin produces.
A genetic heart defect puts it at risk of hypertrophic cardiomyopathy, and the required annual HCM scans cost $150 to $500.
