The Question
“Hey Dr. Paola,
Roxy is a litter box dictator when it comes to my other cat Ivor. I have three litter boxes. Roxy uses the one in the bathroom. The other two are in a spare room. One is used by Ivor. The other box has fresh litter in it. Neither cat has used this box for two weeks now. When Ivor needs to use his box, Roxy will follow him. She allows him to take care of business. He hurriedly leaves and Roxy attacks his tail and back side. Other times Roxy will just sit near Ivor’s litter box for hours on end waiting for Ivor to need to use his litter box. “ – Lloyd
Quick Info about Roxy and Ivor
Hi Lloyd,
Cat relationships are oftentimes challenging and what you’re observing is unfortunately not uncommon in multi-cat households. Roxy’s behavior around the litter box is a form of resource guarding and territorial control, and for Ivor, it’s likely creating significant stress. That hurried exit and Roxy’s ambushes suggest that Ivor may start avoiding the box altogether, which could escalate into house soiling or even stress-related urinary tract issues. Cats are subtle communicators, and this kind of tension often flies under the radar until a medical or behavioral concern arises.
To help ease the tension, I’d recommend making a few environmental changes. Even though you already have three litter boxes, their placement is just as important as their number. Try adding a fourth box in a completely different area of the home, ideally where Roxy can’t easily monitor it. Think of it like giving Ivor a private bathroom away from the hallway bully. Also, consider using calming aids such as multicat synthetic pheromone diffusers in the areas where they spend the most time. Increasing enrichment through vertical spaces, separate feeding stations, and interactive play can help redirect Roxy’s energy and reduce her sense of needing to control shared resources.
If things don’t improve or escalate further, a consultation with a feline behaviorist can offer valuable insight, and an online veterinary service like our own PangoVet could help guide the next steps without needing to establish a full doctor-patient relationship right away. You’re clearly very observant and proactive, and I should congratulate you because that puts both Roxy and Ivor in a great position for improvement.
Sincerely,
– Dr. Paola
