Just an update on my last post. I think I know the reason why my cat Tigger wasn't being himself yesterday. Since I am pregnant, my boyfriend has to change the litter box for me, but he's really bad about doing it, so the box was really dirty. I guess Tigger thought it was pretty dirty himself so he stopped using it (he didn't go anywhere else tho). Last night, my boyfriend finally cleaned the box and put in new litter. Tigger used it right afterwards and peed literally what looked like a cup (there was so much it took a little while to absorb in the litter). I guess he was holding it in so long that he felt like crap himself and he wasn't moving much cuz he was holding it in. And he was barely eating cuz holding in the pee was making him feel sick (or cuz he's strictly a canned food eater, he knew there was too much water in there already and didn't need anymore). After he went to the bathroom, he was playful again with his toy mouse. He acted happy and loveable to me but was mean to my boyfriend. Tigger wouldn't let him pet him (maybe because he associated my boyfriend with cleaning his box and since he didn't clean the box, he was mad at him lol). So I think things are a-okay. I just hope the fact that he peed like a cup (maybe I'm over exagerating cuz it seemed like a lot compared to his usual bathroom stops) isn't a sign of something serious. Can cats have the mentality to think they can hold their urine? I hope he doesn't do it a lot cuz i know that could lead to a UTI (and I know it's more serious for male cats). Anybody else have a cat that "held it in" or peed a lot at one sitting? This is really his first time doing it (he doesn't make frequent trips tho).
