I am watching 3 kittys for 10 days. I am 4 days into it now. I just met these cats 4 days ago. 2 girls, 1 boy. all around 6-8 yrs old. Boy cat goes outside at night, comes home in the am to eat/sleep. I am watching these cats in their own home. I have a 9 yrs kitty--Rosie--who does not go outside. Anyhow...day 2 I notice someone has a runny stool...diarrhea maybe? I am not sure...it was flat,but like putty sortof? I wasn't going to call my neighbor unless it continued. So next day ...2 more runny stools....1 in the morning and 1 that was sortof formed on the end of it in the late afternoon. It was better than the early morning stool but still not solid. Should I be worried here? I called her and she said to give it a couple more days and then maybe she could get her friend to take them to the vet? I did also notice (and this I called my vet on and a really nice vet-tech helped me on the phone) TINY TINY GRAIN LOOKING things--white--like rice but so very much smaller....on her sofa. Now I thought maybe these were tape worm segments--but the vet-tech said that they sound too small to be that. And all these rice-looking things are exactly the same size. Aren't tape segments irregular in size? My kitty has never had tapes so I am not very familiar. I explained really good on the phone what these things looked like and she could not come up with what they might be. I have not seen any of these move...and oh!!!! On one of the cats beds? I found a ton of these things...but they were turned yellow...almost like a golden color. I took the bed outside and shook it out really good ..but it weirded me out. I don't know if the diarrhea had something to do with the grain looking things I am seeing? Or could one of the kitty's just be stressed out 'cuz I am a new person taking care of them and they got a nervous tummy? They are very loving towards me and seem to like me now...first two days one girl kitty would not come out from under the sofa and now she comes right up to me. The other two seemed to like me right away and were not shy. I was thinking maybe the shy kitty had the "runs" cuz she was scared? nervous? Could that be it? Or do we maybe have a worm situation here causing the runs? I don't know how to bring this up to my neighbor because she said they have never had diarrhea in all the time she's had them (6 yrs?) I almost feel like she won't beieve me if I say they might have a worm? You have to really "look" to see these white things....they are on the carpet, on the sofa, on the table....anyone have any ideas? How shoud I word it to my neighbor so she is not offended that I think her cats might have worms? Or should I not say anything? And the stool thing....when is it worrisome --I mean, these are not full-fledged watery stools--but they are not normal either...not normal to what I would consider a formed,shaped,solid kitty poop. What should I do here? thanks for any/all help.
