When to de-worm

How young can you start treating "wild" (wild being that I found them on the side of the road) kittens? I believe they are 4-5 weeks (roaming, teeth, eyes changed, playful). They aren't fully accepting solid soft food but they show interest, so they are on KMR.

Healthy kittens normally see the vet for first shots and de-worming at 8 weeks old, unless they are sick. It sounds like yours should go in about 3 weeks! [emoji]128522[/emoji]

Depends on the vet. We begin deworming at 4 weeks and every 2 weeks after that and we vaccinate at 6, 9, and 12 weeks.
