I have 2 cats and one lab-staffy mix with a pebble walkway that catches every single pine nettle that drops. I sweep every morning and vacuum every week and have just accepted that it's a never ending cycle. Living minimally helps, and less rugs (easier to sweep). Blankets on the couches are a must as well. I have one room (the office/guest room) they're not allowed in, i need ONE space not covered in animal hair and pine nettles and weird dirt (dirt or poop? dirt or poo???) and drool - it helps!
