Have posted similar before but am a bit obsessed.
Mine are spoiled, and as I have no children, I am unapologetic for the money I spend on them.
My cats:
have a cashmere blanket each
have 800 thread count sheets on their day bed
have quarterly vet check ups to nip any health issues in the bud ( old and a bit doddery)
eat organic meat from the farm shop at the weekend
drink filtered water.
We got them for free, but have spent a fortune on them over the years - we can afford to and it makes me very happy to do so.
We also bought our house because it has the ideal, safe environment for cats. The kitchen and layout is a bit crap for humans.
