We have a cat that is about 1 year old and about 6-8 weeks ago she had 1 kitten (yes, I know, everyone says only 1 is weird). Everything was fine, she nursed and they played together and everything. About 5 days ago the Mommy cat disappeared and we couldn't find her for anything! Thankfully, she came back home today, BUT she is very mean to her kitten now! If the kitten comes anywhere near her she hisses and attacks (scratches and stuff). Also, the mommy cat also looks like she may be pregnant again, her belly is enlarged. Please help! I do not know what is happening or what to do...
