Kittens (Bertram)

Weined kittens, not tame but not too crazy.
They were raised by the mama and I handled them very little.
I dont know what breed they are.
Parents are great at catching mice and other critters around the farm.
No charge but any gratuity would be appreciated and would go towards spaying and neutering the parents.
Any information on cheap/free spay and nuter programs would also be appreciated.
