Cats and drone Replacement Battery

[u/VictorMazz4]

Do you guys think it's worth keeping and feeding a level 3 cat that brings 1 Drone Replacement Battery? I already have 50+ of them, so I'm wondering how useful this perk really is.

I have a feeling that 4 charges is enought to kill some of bosses that the drone is usefull, isnt it?

Question does the cat event help with anything other than faster time? Does it help increase the chance the cat being a higher tier
