Senior Cat Claws
Senior cats' claws thicken due to decreased activity. They scratch less which makes it difficult for them to shed their claws properly.
Dirt and fur trapped underneath their claws plus the increased thickness makes it less retractable just like Cinders' Dew Claw ('thumb' claw) here.
Unless the claws are trimmed, walking will become difficult. Untrimmed claws may grow into the pads causing pain.
