Taking clerics on every run

So i noticed my breeding rooms are filling with white cats and kittens getting lots of cleric abilities bc I just dont feel good about starting a run without a cleric. When im picking out which cats to take on an adventure my first question is "ok who can be the cleric this time."

Thing is, I did do one run without a cleric, and literally all 4 cats got offered some form of healing. Is there some secret mechanic where you are more likely to get heals if no cleric? Also I havent unlocked all the classes yet, only just got butcher soo..

Basically just want to know how people get by without a cleric. I was putting collars on cats and realized I had an awesome setup like really good Fighter/Mage/Tink/Thief but then I was like wait... no cleric...

Do you guys just ignore the need to have a cleric and hope for the best or always take a cleric like me?
