I have a five month old kitten who was found very young (two to three weeks old) without a mother. So, he was bottle fed from a very young age. He has been treated for giardia several times; twice by the shelter we got him from and once by us and our veterinarian. However, I'm now wondering if he's ever been cured. I noticed a few days ago that he kept getting fecal matter on his tail. He does curl his tail at times so I didn't really think it was a big deal and just cleaned it up with warm water and a rag. Then he started sleeping more than usual two days ago. All day yesterday he seemed pretty lethargic and is acting like he doesn't feel well. His last bowel movement was really runny and contained a lot of mucus. I know he needs to go back to the vet but, due to my own recent major medical emergency, we are really struggling financially right now. I didn't notice him acting sick last time, is this normal with giardia? Can giardia be deadly? I will get him to the vet as soon as I possibly can, I just wanted to get an idea of how urgent this is. I'm so worried about him and wish we weren't in the situation we are in. I'm praying we find relief today and I can get him to the vet.
