Cat dilemma

The thing is this cat came to my home (more like dibuang by her previous owner I supposed as she's in a very good condition when we found her) when she was just more or less like 2 months old kitten. Mum pitied her and she said that we'll just take care of her till she's good enough to survive on her own then we buang her at some nice eating place (not a 5 star eating place. Just at some hawker centre where she can get food easily). But I grew fond of her - I have a very soft spot for animals - and decided to adopt her, somehow.

And then the dilemma..

I never actually adopt a cat before. I mean before this I do have a cat and he was absolutely an outdoor cat. We never let any cats to enter the house as my sister has athma and thus it's bad for her. Before this we only feed him. Just that. No sangkar, no shampooing, no neutering.

This cat however is different. She loves jumping around! So, I bought her a sangkar just to put her inside when I want to go to work so that I won't ran her with the car accidentally.

Then she gets pregnant. She's so gatal! =) And she gets smelly. I make some research on the internet on how to care for a pregnant cat, how to bathe her, when to get her spayed etc. Then suddenly, the realisation that I am adopting a cat and caring her for real, came rushing into me. Part of me really want to give her all that. I mean bathing her, getting her spayed and buy her a new sangkar - an expensive one at that, RM 200!! - because the current one is quite small and I foreseeing her to be in the sangkar with her babies for about 2 - 3 months before I spayed her, treats and all that. But another part of me was like, you know just treat her like any normal cat. Just feed and nothing else.

What to do?
