Every time I try to adopt a cat, something unexpected happens and the deal gets cancelled

I really want to adopt a cat but something comes in the way Like once the real owner of the cat was found Another time I got dengue on the day I had to go and collect it My parents told me it's not a good sign to keep a cat as a pet I don't want to force it to be at my place I'll take care of it for a month and let it go wherever it wants to I really really want to have a kitten Most of the times I feel lonely and wouldn't it be great when yk that someone is waiting for you at your home
