STells, all your dream objects fit together really well.
Kittens are about little nagging problems and issues. You had your little kitty in not one but two plastic bags. So maybe there's something bothering you that you feel you've got under control, or maybe worry whether or not you do. Thunder usually means you've got some anxiety over some issue, and rain can mean anything from "washing away the old" to forgiving. Evil is pretty easy to interpret... usually means anger, hate, resentment, possibly over something you haven't confronted or squashed down into yourself.
The meaning of the apartment is simply that it's a vessel for the story your created in it. The situation you've dreamed about is separate from your life with your husband/family. Perhaps they're involved somehow, but you see it as "your" situation to handle on your own.
Cats, like the one that came to you which you locked back in the apartment, symbolize (duh) femininity and also independence. You said it was yellow, but didn't say what kind of yellow, or maybe if you meant it had more of a gold-yellow coat. Yellow, if the cat was an ugly yellow, can mean discord, or upset, and since you kept it in the apartment... could be bolstering your feeling that it's something you are keeping to yourself and want to resolve or take care of on your own.
The radio (kind of obviously) is all about communication, so it's interesting that the communication symbol occurred either before or after you entered your "box 'o anxiety" (I say anxiety, but could be just a small prob you focussed on) so maybe you feel there is a lack of... or alternatively, that you don't want to communicate whatever it is. The person being reported about isn't necessarily the focus of your dream, could have just been random because Getbig was on your mind before you went to sleep.
It's usually easier to put these things together when you know what's going on in someone's life --- cause it may not be a problem or issue at all, just a situation you're keeping for you... but like I said, your dream symbols all tie together so well.
Sweet dreams!!!
