<prompt> Human: Some quick background: Im a 26F with annual salary 32k and debating changing careers to something that pays high read: might be a student again soon. My bf and I live together and have indoor cats. Ive never owned indoor cats and have discovered that Im allergic to most litter and the ones Im not allergic to are not effective. My bf took on the litter responsibility because of my allergies but he is not able to clean it as often as is needed. Ive been debating a 450 robotic litter box but am unsure if its a justifiable expense.TL;DRHow do you decide whether to purchase a luxury item? What steps would you take and how long would you wait? What factors need to be considered?  <response>: I try to realistically appraise the value it adds to my life, versus the more practical uses of that money. 450 for a device that saves you 10 minutes of work, especially when you consider the fact that it will probably wear outbreak within a year or 2, I would definitely classify this as not a smart purchase.
