I have a few cats and occasionally breed purebred kittens, which I’ve been doing 25 plus years and my mom even longer. We’ve never had any issues and they are house cats, not in cages or anything. Recently we had some issues with diarrhea which escalated in some cases, and after much back and forth and testing, fecal samples found giardia, which is actually a relief as we know how to treat it.
After much research, it seems Panacur/fenbendazole/Safeguard is one of the best treatments. Hubby is a large animal vet and loves to look this up, and my best friend is a feline specialist who’s never heard of using it, but gives me feedback. (I also learned Marquis, which is a horse wormer (at $200 a tube!) for EPM is a primo treatment for coccidia.) This is good news as the other traditional treatments don’t work (metrabendazsomething) and are so nasty tasting (sulfa drugs) the animals hate them. It’s also way safer and less toxic than everything else. It’s also an overall wormer and gets most anything, though maybe not all tapeworms. (You can use Drontel for that.)
So, I’m using the leftover Pancur from the horses to dose them initially for 3 to 5 days and getting every cat and the dog at the same time, and ordered the Safeguard cattle/horse suspension for the future. The don’t sell the suspension in the US for cats, only dogs, and the 10% 100 ml for dogs is $38, while the same thing for horses is $120 for 1000 ml. 1000 ml can treat a lot of cats and dogs for years, so if you have more than a few, it’s a huge moneysaver. They push the powder for dogs/cats here, which is about $4 a dose. For 10% solution, the dosing is .2 cc’s/ml’s per pound, or about a cc/ml per 5 lbs dogs/cats/horses.
I’m going to switch over to a worming protocol, which I never did officially. I was doing pyrantel pamoate periodically at 2 week intervals with kittens to get roundworms (which are in mother’s milk.) From what I’ve read of big breeders of dogs and cats, they do the same kind of thing with kittens and puppies with Safeguard to regularly worm and keep down chances of giardia and such. I’m not 100% sure if they do it every two or three weeks and if it’s just one dose, or a three day dose. Every animal in the house is dosed at the same time.
So, if you don’t have this information, this might be useful. If you do, I’d love feedback on what you’ve done in what situations.
