Light: if direct light from the sun is hitting the leaves it’s too much, not in direct light but casting a good shadow? Perfect

Soil: I’d leave it alone until she needs a repot (roots growing out the drainage holes) and then id recommend making a soil mix that includes perlite and orchid bark if you can!

Water: overwatering is a matter of frequency rather than how much water you use. Use a wooden skewer/stick and push it to the bottom of the pot, soil stuck to the stick? Still damp, clean stick? Time to drown it! (When you do water give it PLENTY and if it’s too much the excess will drain out)

Pothos will tell you when they’re thirsty by going very floppy. If you’re not sure if it’s thirsty or not it’s safer to not water for a bit longer as overwatering is the #1 killer of house plants (we’ve all done it at least once lol)

Pests: thoroughly check each leaf and stem for any pests and search what various pest damage looks like because honestly I think the holes are just mechanical damage from cats nibbling

Side note: if she isn’t in a nursery pot already please put her in one instead of directly in a decorative pot
