Kim, my 2nd cat was disappeared since last Monday evening.

It hurt me hell. I love her as my own baby.
That´s time Kim was "horny" to want to have tomcats but I kept her in the house last December. It gone in 2 weeks later. ***phew*** but it come again last weekends.
Kim become horny last Friday and scream for want go outside to have sex.... We tried so hard to keep her inside the house until last Monday evening. My hubby open the door without notice that Kim is around and escaped out of our house. It´s too late for us to notice it. We look around but Kim disappeared for the good. It upset us total.
Danny, my oldest son told me what his friends told him what they has experience with their cats before. They said that female cats look for tomcats to have sex then will come back to us when it´s over.
Is it true?
I can´t image because she gone for almost 5 days now.
We want to have Kim operation to prevent to have kitten last January but operation cost $ 218. (€170). It´s too expensive so we wait until this summer because there´re alot of bills we pay during winter time.

I wish to have her operation last Janauary instead of wait until this summer...
We were shock about operation cost because we remember when we had my Sussi, (my soon to be 19 years old cat) operation cost was 90 Deutsche Marke ($59.) in 1987.
