rescue and neutralize

[soyouz]

Hi,

If I rescue a cat with the babies , I would like to neutralize them before given them to adoption, does veterinary are affiliated with rescue group ? because I don't want to pay the operation for all the kittens ... but I want to give the adoption fees to the rescue/veterinary . Could someone inform me how it work ?

can I rescue animals and after ask for help to a shelter/rescue group ?

because sometime it's an emergency and in the laurentides there is no rescue group

thanks for the information
