Well this is exciting. Is the mom and 5 kittens from a shelter? Make sure mom has non stop high calorie kitten food. Esp soft food but I leave dry kitten food with mom also. I offer goats milk to the moms when nursing.
Keep an eye on those babies. Make sure they are all thriving. I cant wait for pictures and see what the mom looks like too. Hats off to you again! You are making such a difference in the future of these cats lives.
