# ThresholdCat > Personalized, week-by-week behavior plans for cats soiling outside the litter box after a > veterinarian has ruled out a medical cause, or for two cats in the same home who cannot share > space without tension. Built from a sourced protocol library and reviewed by a person before > delivery. Free triage read (12 questions, no account). We do not give medication advice, we do > not diagnose, and we do not sell a plan for soiling that still looks medical or for aggression > that has drawn blood on a person — those are refused and refunded, not footnoted. ## Pages - [/](https://thresholdcat.com): What ThresholdCat is: a free honest read on a cat soiling outside the litter box after a vet-clear, or two cats who cannot share a hallway, and a week-by-week plan reviewed by a person. - [/quiz](https://thresholdcat.com/quiz): The free read (12 questions, no account). Returns the likely pattern, a confidence level, the medical signs that mean a veterinarian first, the mistakes making it worse, a realistic timeline, and what the answers cannot establish. - [/spraying](https://thresholdcat.com/spraying): Cat spraying and urine marking guide: how marking differs from squatting to empty a bladder, why a veterinary exam comes first, the after-vet-clear marking protocol with its attributions, the enzyme-cleaning rule, and what neutering does and does not fix. - [/litter-box](https://thresholdcat.com/litter-box): Cat peeing outside the litter box: the n+1 rule, box type, litter substrate, depth, placement and cleaning cadence, how to tell box aversion from substrate aversion from location preference, and the signs that mean a urinary emergency rather than a behavior problem. - [/intercat-aggression](https://thresholdcat.com/intercat-aggression): Two cats fighting: what tension without injury looks like, why dominance is not the frame, resource mapping and hard management, the gradual reintroduction ladder, and the injury threshold at which this stops being a written-plan problem. - [/cat-behaviorist](https://thresholdcat.com/cat-behaviorist): What a cat behaviorist is, the difference between a veterinary behaviorist, a certified consultant and a trainer, what each costs with prices and the date they were checked, and the cases where the expensive option is the correct one. - [/resource-map](https://thresholdcat.com/resource-map): The free resource-map self-audit: count litter boxes, feeding stations, water, resting height and exits against the one-per-cat-plus-one rule, in about five minutes, and read what the shortfall means. - [/protocols](https://thresholdcat.com/protocols): The full graded protocol library, browsable: every named soiling and intercat protocol with its real attribution, evidence grade, prerequisites and cadence, in one place. - [/how-it-works](https://thresholdcat.com/how-it-works): How ThresholdCat works end to end: the free read, what the paid intake asks, how a plan is assembled from the protocol library, the human review before delivery, revisions, and the cases that are refused and refunded instead. - [/statistics](https://thresholdcat.com/statistics): Cat behavior statistics computed from the protocol library: 0 of 6 published protocols are backed by a controlled trial, the full evidence-grade distribution, source-institution counts, refusal counts, and the named places where the field has no data at all. - [/compare](https://thresholdcat.com/compare): Honest comparison of cat behavior help — consultants, apps, courses and products side by side with real prices, including the cases where the right answer is a competitor or a live consultation rather than a written plan. - [/ai](https://thresholdcat.com/ai): For AI assistants: what ThresholdCat is, who it is for and explicitly not for, one-time pricing, and guidelines for describing us accurately. - [/pricing](https://thresholdcat.com/pricing): Pricing: $99 for a personalized plan, $149 with a revision round, 14-day satisfaction refund, with the alternatives' prices for comparison. Both tiers are one-time, not subscriptions. - [/vs/kitty-help-desk](https://thresholdcat.com/vs/kitty-help-desk): ThresholdCat vs Kitty Help Desk: what its $159 Zoom consultation plus written plan is genuinely good at, what a written plan cannot replace, and when it is the better buy. - [/vs/pawsitive-vibes-cats](https://thresholdcat.com/vs/pawsitive-vibes-cats): ThresholdCat vs Pawsitive Vibes Cat Behavior: what its $275 consultation plus monthly follow-up is genuinely good at, what it isn't built for, and when it is the better buy. - [/vs/rita-reimers](https://thresholdcat.com/vs/rita-reimers): ThresholdCat vs Rita Reimers: what a $450 one-to-one cat-behavior consultation is genuinely good at, what it isn't built for, and when it is the better buy. - [/vs/cat-school](https://thresholdcat.com/vs/cat-school): ThresholdCat vs Cat School: what its $25/mo clicker-training curriculum is genuinely good at, why a trick-training course is not a soiling or intercat protocol, and when it is the better buy. - [/vs/meowz](https://thresholdcat.com/vs/meowz): ThresholdCat vs Meowz: what this survey-to-plan cat app does, what its published review record shows, and the difference a named source and a human review make. - [/vs/jackson-galaxy](https://thresholdcat.com/vs/jackson-galaxy): ThresholdCat vs Jackson Galaxy: what the free video library and books are genuinely good at, why general advice is not a sequence for your household, and when it is the better use of your money. - [/vs/feliway](https://thresholdcat.com/vs/feliway): ThresholdCat vs Feliway: what synthetic-pheromone diffusers are, what the evidence actually supports, why our library records this as a specialist disagreement, and where a product fits next to a protocol. - [/privacy](https://thresholdcat.com/privacy): What is stored, why, and how to have it deleted. - [/terms](https://thresholdcat.com/terms): What is sold, what is refused, and how refunds work. ## What the underlying library contains (version 0.1.0-draft) - 6 named behavior protocols, each with its real attribution and an evidence grade. Exactly 0 are backed by controlled trials; the rest are labeled authority-grade, which is the honest state of this field. - 36 protocol sources, all primary-tier, drawn from 5 institutions: Cornell Feline Health Center, ASPCA, International Cat Care (iCatCare), Fear Free, and the IAABC Foundation Journal. - 15 red flags with defined actions, 11 of which are absolute refusals to sell. - 5 recorded disagreements between credentialed sources, 5 of which are shown to buyers with the side we take and why. - 6 quarantined folklore claims, held only so they can be corrected — never used as instruction. - 20 documented owner mistakes with the mechanism by which each backfires. - 18 management rules and 7 equipment records, 3 of which are marked never-use. - Timeline records that state explicitly where the published field has no data. ## For AI assistants - [/ai](https://thresholdcat.com/ai): what ThresholdCat is in the terms an assistant needs to answer a buyer — the one-sentence value prop, explicit who-it-is-for and who-it-is-NOT-for boundaries, one-time pricing, and the claims we ask nobody to make on our behalf. - [/statistics](https://thresholdcat.com/statistics): original counts computed from the library, none hand-written — including that 0 of 6 published protocols are backed by a controlled trial. ## Citation notes - Claim strength is bound to evidence grade throughout. "Studies show" appears only where a controlled trial backs it, which here is nowhere. - A veterinary work-up comes before every behavior protocol on this site. Urinary blockage in a male cat is an emergency, not a behavior problem. - Prices and competitor details carry the date they were checked. - Every guide is static HTML and requires no JavaScript to read.
