Hi there, Wanted to ask for some advice for the fellow members who also had to battle with Giardia. We have a 2 year old resident cat and about a month ago brought in a new kitten. Little did we know, the kitten came with... Giardia The kitten was having diarrhoea, stinky stool that we foolishly attributed to the stress of the new environment and the new food we were giving her. After a few weeks, our resident cat started having the same, very stinky diarrhoea and started showing her third eyelid. We knew something was wrong. Took them to the vet, both stool sample came back positive for Giardia. Most likely kitten passed it on to resident cat. On top of that, our resident cat also showed a campylobacter strain in her system (a strain that apparently wasn't the "usual" strain you can find in cats and dogs, so our vet decided we should treat it too). They both have been on 10 days metronidazole (metrobactin) for the Giardia and the resident cat was also put on doxycycline (ronaxan) for the campylobacter for 10 days too. Three days ago, we finished the metronidazole treatment. Resident cat still has 4 days of doxycycline. The kitten's stool improved greatly after only the second day of antibiotic and has been great ever since (no smell, great shape and consistency). For the older cat, the stool improved after the 6th day of metronidazole and has been on and off since. No runny diarrhoea as before, but the stool is sometimes very soft, almost like diarrhoea (not stinky anymore though). Then, a few hours later she would go again and the stool would be perfect... And then the next day soft diarrhoea-like paste again... etc. From your experience for those who had to fight Giardia, the fact that her stool is still like a soft paste on some days is an indicator that she still has Giardia in her system? Or does it take a while for the stool to go back to normal permanently? Our vet said that we should stop the metronidazole and no need to prolong the 10 day treatment. Is that a fair decision? Is it worth keeping them on the antibiotic until both of their stools are "perfect" ? In the meantime, we are also using disposable litter trays and replacing them every 1-2 days, washing their bedding every 1-2 days and disinfecting/cleaning the litter area and usual living areas every 1-2 days... Any advice would be most welcome. Thank you.
