It's a good thought, but no, I'm pretty confident she isn't using his box. Most of the time it's with him in his room when she's out, and the rest of the time she rarely goes into the French door room (where his box is). But I will watch carefully now."Thanks for your feedback!" - You are welcome.
" I've looked back over her peeing and it has sometimes been x2 per day, but in the last few days really only once every 20ish hours - like evening the one day, then afternoon the next day, etc. I've been tracking it now because it seemed so infrequent.." - Yeah, I don't like that. Any time there is change it is something we need to look at. Do you think she is drinking less? Eating less wet food?
" It's nowhere near as often as Hawthorne goes." - Yes :/
" I think she drinks enough - I see her drinking at least 2 or 3 times a day. And she gets primarily wet food, although I guess there are quite a few kibble treats in there." - Ok. It sounds ok. Is it warmer or drier than usual lately?
"The kibble is formulated to support urinary concerns - Hawthorne has had a UTI before. I haven't seen her grooming the area or focusing attention there, like as per a UTI. But I haven't seen her pee so I can't tell about straining." - Ok. Hmmmmmm
"I've only taken her to the vet once before, when I first adopted her. I don't think she loved it, no. But she seemed to do ok." - OK, good to know.
"I'll have her sleep with us again tonight and see if she pees in the box." - I think that is fine. I have a feeling it was a bit of stress/separation anxiety. BUT I am bothered that she may not be peeing as much. Do you think there is any chance she is using "his" box?
"If not, I'll book an appointment. Best to be confident it isn't medical." - Yes, it never hurts as long as they don't get too stressed. Sounds like she would be ok.
Keep an eye on her and let me know and also see if she may be using :his" box. I just wonder if she is.
I have a vet appointment for tomorrow afternoon. I'm also trying to add some water to her wet food and to her salmon snack, so she's getting more liquid like that. See if I can increase the amount she's drinking/consuming.
After we see overnight, I'll also think about maybe a bigger litter box.
Do you think if it were stress about Hawthorne specifically it would have been happening more often/earlier than this? I just want to be sure it isn't the intro process adding to her stress/anxiety.
