We are OVER RUN with stray cats, and we don't have the money to get them fixed, especially since they aren't really ours. One had babies in April. We only have two out of that litter, but one refuses to quit nursing! He's four months old, and after he was seperated from his mom and her milk dried up, he's started nursing off his older sister! She is barely producing milk and can't even feed her own babies as it is! Why won't he stop? Has anyone else seen them nurse this long?
