Well it´s not hard,just the problem for me is my terrible English. It´s always barrier for me in learning Turkish. 
I could translate this sentences into my language. ~ 

Good try nemanja but the translation of fifth sentence is problematic. I dont know how to translate it literally too.

My try:

I am enough handsome to make an orangutan jealous.

Ohh it was accusative,I haven´t seen the ı in the end...orangutanI

This reminded me of a Dutch man who used his dead cat to make an unusual quad-copter. Pervaneli bir kedi

zavallı kedi...

Nice post. It wil really help me in learning turkish. I am learning it and if there will be any problem i will definitely share it here to get good help.

Wow it really flies. But why is it dead?

The cat was run over by a car.

And now I have some translation questions, and hope to learn 

But why is it dead? Ama neden öldü? [Kedi neden öldü?]

A car ran over the cat. Bir araba kediyi çiğnedi.

The cat was run over by a car. Kedi arabayla çiğnendi. (passive)

Bunlar doğru mu?

kedi´un bir kalp hastal1g1 var.  kitty has a heart condition

kedi aklında cok hicbir sey degili var kitty has alot of nothing on his mind

kedi az konusan degil meow bir

thank you

Kediciğin kalp rahatsızlığı var.

e to t

dead kitty is a perfect pet, won´t eat your food, make a mess or shed any hair on your black clothes. Will not wake you up to go outside.

Yes.

Ölü bir kedi harika bir evcil hayvandır. Yiyeceğinizi yemez, etrafı mahvetmez, siyah elbiselerinize tüylerini dökmez. Sizi dışarı çıkmak için uyandırmaz.

you do not wake to go out  - seems wrong

the advise of day: dont give up to love..

 I am so handsome it would make an orangutan jealous.

(Not me -- just translating. I am so beautiful it would make a mermaid jealous.)

 Kes, I agree with gök.

Sizi uyandırmaz - does not wake you up.

Here "you" is the subject of the verb "to wake someone else up".

The -dır- bit in uyandırmak is the causative:

uyanmak = to wake up

uyandırmak = to wake someone else up (lit: to cause to wake up).
