It really does help the babies to get visited.
My friend "Auntie Jan" comes to see my babies (Stella, Gracie and Tigger) when I am gone for more than the day. She spends a bit of time giving them some loving and treats, on top of the bowl and box check. So I just get the normal close herding and cuddling when I get home. I get escorted everywhere.
Then when Jan is out of town, Auntie Shubie kicks in and I visit her babies. 2 need meds, but have adjusted to me administering them - except Hershey - he hisses at everyone except his Mom!
Sounds like a good "kitty auntie or uncle" is in order!
