The Litter Tray Worries Veterinarians Keep Raising — and What the Guidelines Actually Say

Ask a room of veterinarians and vet nurses about litter trays and the same handful of worries comes up every time. They are not complaints about litter — they are concerns about the tray itself, and they are well documented in European Advisory Board on Cat Diseases (ABCD) and American Animal Hospital Association (AAHA) infection-control guidance. This article walks through the five concerns raised most often in practice, what the published guidance actually says about each, and where a single-use tray answers them structurally rather than procedurally.

1. "The tray is never really clean between patients"

This is the most fundamental worry, and the guidance is blunt. The ABCD disinfection fact sheet states that litter trays should be sterilised between occupants — with boiling water or steam — and, failing that, that single-use cardboard trays that can be incinerated are an acceptable alternative. Most clinics do not have a practical way to boil or steam a plastic tub after every patient, which means the tray quietly sits outside the written hygiene protocol. A single-use tray removes the sterilisation requirement entirely: the tray is the consumable, and between-patient hygiene is achieved by disposal, not by a process that depends on staff time and hot water availability.

2. "Disinfectants are a risk to the cat, not just a solution"

The second worry is the chemicals themselves. ABCD's disinfection guidance is explicit that the cat is exquisitely sensitive to certain chemicals, and that toxicity can occur through ingestion during grooming, absorption through the skin and foot pads, or inhalation of irritant fumes. It also notes that organic matter inactivates most disinfectants, and that residue should be rinsed away with clean water — a step that adds time and is easy to skip on a busy ward. Every cycle of scrubbing a reusable tub is therefore a trade-off: incomplete removal of pathogens, or chemical residue inches from a recovering animal. A tray that is used once and discarded needs no disinfectant at all.

3. "Faeces and urine are where the pathogens are"

The third concern is that the litter tray is the single highest pathogen-load surface in the cage. ABCD's shelter guidelines and the AAHA infection-control framework both treat faecal-oral transmission as a primary route for the organisms that matter most in multi-cat environments — panleukopenia virus, Giardia, Tritrichomonas and enteric bacteria among them. Cats can also shed organisms such as Leptospira in their urine, which is why ABCD guidance flags urine as a source of contamination with zoonotic relevance. When the highest-load surface is also the one that gets reused, it becomes the weakest link in the chain — which is exactly the argument for making it single-use.

4. "Dusty litter is a respiratory and surgical problem"

ABCD guidance also advises against dusty cat litters in clinical environments — a point veterinarians echo for respiratory patients, post-surgical patients whose incision must stay clean, and asthmatic cats. The tray choice and the litter choice work together here: a clean, single-use tray filled with low-dust paper or wood litter removes both the reused-surface risk and the airborne-particle risk.

5. "We don't have time to do this properly"

The fifth worry is the one nobody writes in a protocol: time. Sterilising or thoroughly washing, disinfecting, rinsing and drying a plastic tub between patients takes real ward minutes, and on a short-staffed day it is the step most likely to be compressed. Guidance written for the ideal scenario assumes a process that busy wards cannot always sustain. Designing the tray as a consumable aligns the protocol with the reality of the rota — the correct action is also the fastest action.

Where VOLKOS fits

VOLKOS treatment boxes and litter trays are moulded from plastic-free plant fibre, sized for cage and ward use (M 40×30×9 cm, L 45×35×11 cm), and supplied in clinic packs of 30 or as a 3-piece discharge set. They are intended to be used once and discarded with compliant waste — which is precisely the alternative the ABCD fact sheet names when sterilisation between occupants is not achievable. Nothing to scrub, nothing to rinse, no chemical exposure for the patient, and a between-patient routine that holds up on the busiest day of the week.

The concerns above are paraphrased from the veterinary guidance cited below. Product dimensions are VOLKOS specifications.
