All is well in the porch. All three of them can already eat raw food now, including Creamy.
There is peace in the porch now, Misty does not bully Creamy as much as before. Actually, Misty is very friendly to me now. More friendly than Samantha!!
Even though they can totally eat raw now, I will still give them canned as they are CNRM-cats and might one day need to be fed by someone else. Kibble as the occasional in-between meal snack.
