I have been feeding a cat who comes around for the past year and a half you can't get ant nearer than 3', she showed up looking emaciated and tired three weeks ago so I put out food and water which she ate. She then brought a litter of kittens and put them under my back deck. For some reason after a week and a half she took three and left two or two came back. I've been feeding them wet kitten chow with kitten formula. they now are eating dry kitten chow appear to be 6 weeks old and are staying on my enclosed porch as there are too many preditors around and ,moma shows up once or twice a day and I let them out to nurse,I'm not sure I doing the right thing, they use the litter box on the enclosed porch and I can handle and play with them and will have them vet checked soon, should I stop letting the mother interact with them, I can't leave them outside as she doesn't stay with them.Help!any suggestions would be appreciated I can't bring them in until they get vet checked as I have indoor cats.
