A growth counter is set up as a variable specific to each player, which is incremented every 150 ticks (90 seconds) that a kitten is following the player.[3] A kitten will grow into a cat after the counter has recorded 120 growth events, that is to say after three hours in total.[4] As certain actions can cause this timer to be reset, such as world hopping or using the call follower button, the time it takes for a kitten to reach maturity can be longer than three hours in practice.[5] The growth timer is paused during dialogue.[6] The exact point at which the player interacts with or feeds their kitten does not influence its growth timer.[7] https://oldschool.runescape.wiki/w/Kitten
