Judging from the picture and weight I’d say they’re around 5 weeks old. Raccoon babies weigh between 500-700 grams at 5 weeks. They gain weight much quicker when on formula. I have one now that’s just barely opening its eyes and he weighs almost 500 grams! He still has the broader nose of an infant raccoon.
At this age they probably won’t eat solid foods because they don’t have their molar teeth. It’s a long process to learn that food is meant to be chewed and swallowed and not just sucked.
If you want to try them on some solid food I’d recommend a small piece of banana. You can put it in their mouth and they may or may not spit it out.
They also must be stimulated to potty just like a squirrel. Be very careful of their stool and wash your hands thoroughly. They can carry roundworm and the eggs.
Do you have a rehabber that can take them if mom doesn’t come for them? Or are you going to raise them?
