I currently have three types of thyme growing in a long planter box but my English Thyme has gotten very woody, sparse, and seems to have stopped growing. My Silver Thyme and Chicken Thyme are still doing fine. I have also discovered that one of my cats likes to sleep on my English Thyme when I'm not looking but now I've put some pots of chives in front so he can't climb into the box. I've also taken some cuttings and put the softwood in water to try help it take root, one of the cuttings has simply died and the others are yet to root but I'm confident in at least two of them. How can I rejuvenate my thyme to make it grow again and be able to harvest it properly?

It would help to add a crushed aspirin tab and honey to that water, and do this daily. This will force rooting rather quickly.
These plants will usually benefit from a hard pruning, and a feeding once they recover. This article will help: https://www.gardeningknowhow.com/edible/herbs/thyme/pruning-thyme-plants.htm
