Am very sorry to read about what your daughter’s been through. Just awful. I hope she will eventually make a complete recovery. I also use clumping cat litter for my cat’s litter tray and have noticed with some brands (including Pets at Home’s own brand, how much the dust rises on filling up the tray). I was in LIDL the other day and bought a bag of their own brand clumping cat litter but I have yet to see how it is - for an absolute bargain price of £2 I am not expecting much, but will see…..
Re the comments made about toxoplasmosis, it is just not when one is pregnant that you catch toxoplasmosis! However, the window of opportunity is the important point and it also has to involve a cat who is habitually outside and is a hunter. If they catch a rodent (who, incidentally, will not be afraid of the cat if it is infected with toxo, therefore “allowing itself” to be more easily caught), the cat will become infected and within a few days, start to eliminate the cysts. These will not become dangerous as such in the first days and so regular emptying the litter tray means you would probably never be exposed. After a few days, the cysts undergo rapid changes in the faeces and this is when they become dangerous.
In a few cats, normally those with a serious chronic disease such as Felv or FIV, but also cats who are not in this category but perfectly well, can develop clinical toxoplasmosis if they have been messing with an infected rodent; it’s rarely seen and usually therefore missed initially off of differential diagnoses by vets. The signs are a very high temperature of unknown origin, hiding, malaise, off food, etc. If not treated immediately with the only effective antibiotic (clindamycin), the cat will be dead within a week.
Sorry to go a bit off-piste ….. but people don’t usually know if they have got toxoplasmosis unless they become immunocompromised. For pregnant women, it just makes sense to get someone else to change litter for all sorts of reasons, but it is generally thought that toxoplasmosis is usually caught by eating undercooked meat, steak tartare, things like that and that is just as important for pregnant women to be mindful of and to avoid.
