Need help – 5 Kittens and their Mommy

I am asking for everyone and anyones help to have these 5 little angels, and their mommy fixed.

They were born 23rd of November 2013 , they are coming close to being 3 Months , its time to start planning on getting them fixed and neutered. 

The mother was an outdoor cat and is itching to go back out. I am afraid she will run out before she is fixed and has another litter. There are so many outdoor cats these days, they all keep repopulation and my fear is these kittens will end up pregnant also, and the circle dosnt end. 

I am really hoping to Fix her and her 5 kittens and get their ears checked for Mites.(they all keep scratching)

I know it will be over costly for 6 cats, I have some money to put towards it but unfortunetly I can not afford all 6 of them. I want them all in perfect shape to find loving homes.

Money saved : 450$                   Estimated cost for all 6 : 1000$

 Any money raised that is above the cost of the surgeries will go to a local rescue, they help provide medical attention, food, collars, cages, foster families and more...

Please, Every little bit helps.
