she does phantom spraying against the wall, doors (including cupboard doors), my bed, my roommates bed.
Brief Answer:
The term “phantom spraying” suggests that you are observing the postures and behaviors associated with spraying (backing up to a vertical surface, tail quivering, treading with the back feet) but may not always see a visible fluid or smell a strong odor, or perhaps the volume is extremely small and quickly evaporating.
However, in behavioral terms, this is almost certainly true territorial marking driven by deep-seated anxiety and insecurity, even if the visible signs are minimal.
The critical factor is that she is marking boundaries (walls, doors) and high-value, scent-rich objects (your bed, your roommate’s bed).
Since you are unsure of the cause, the first, most cost-effective step is a full veterinary examination to definitively rule out any medical issue, especially since your cat targets soft and porous surfaces like beds.
If medically clear, you must immediately implement comprehensive stress reduction and environmental security measures, following the natural-instinct protocols in Cat Spray Stop by Susan Westinghouse, alongside the consistent use of Feliway MultiCat diffusers to restore her sense of security within your shared home.
Detailed Answer:
The behavior you describe, targeting walls, doors, and especially the beds of you and your roommate, is a classic pattern of territorial marking.
Your cat is asserting ownership and diffusing her scent in high-traffic, high-value, and contested areas.
The distinction you make, “phantom spraying,” may relate to the highly concentrated nature and small volume of a true territorial spray, which can be less noticeable than a full urination, or it may simply be a behavioral display that sometimes occurs without any actual fluid release, though the latter is less common.
Because she is targeting your beds, this introduces a crucial consideration: aversion to the litter box.
Cats often seek out soft, porous materials (like bedding) when they are experiencing pain during elimination, which they associate with the litter box.
Before proceeding with behavioral remedies, you must rule out conditions like a Urinary Tract Infection (UTI), bladder stones, or even high anxiety that leads to cystitis.
A comprehensive veterinary panel is essential; it is a critical, one-time investment that saves you from months of ineffective behavioral efforts if the problem is medical.
Assuming the veterinary check is clear, the issue is environmental stress and territorial competition, potentially exacerbated by the presence of your roommate and any other household changes.
To resolve this, you need a multi-faceted approach as detailed in Cat Spray Stop.
First, address the resource access.
Ensure there are enough litter boxes (the N+1 rule: N number of cats plus one extra) that are kept impeccably clean and placed in quiet, low-traffic areas.
This minimizes the chance she is avoiding a box due to placement or lack of cleanliness.
You should offer different litter substrates to see if she has a preference.
Second, manage the anxiety.
Deploy Feliway MultiCat diffusers in the rooms where the spraying occurs, especially near the doors and beds, which are her primary targets.
These pheromones create a calming, secure atmosphere, directly mitigating the stress that drives the marking behavior.
This is a scientifically supported, non-invasive, and cost-effective way to change her emotional state.
Third, restrict access to the highest-value targets (the beds) temporarily by closing bedroom doors or using waterproof covers, and substitute this with a designated, highly desirable, scent-safe spot for her.
Ensure she has ample vertical territory (tall cat trees, shelves) and safe hiding spots that are uncontested.
By increasing her overall sense of security and control over her environment, you reduce her perceived need to spray, breaking the cycle of territorial communication and ultimately saving you from having to replace soiled furnishings.
