Hello to all. I have russian tortoise already for about 33 years. For about 6 or more years he has chronic kidney disease. Since september little by little he stopped urinating and later pooping at all. At vet hospital he started to poop and urinate every second - third day, so i took him back home. Vet told me, that there was stuck a lot food in his intestines and also his urine was pushing each other, so nothing could get out. Now, at home, i have him already for a week, but he only pooped once and urinated a little twice. His weight is growing again. His appetite is good, but i feed him only each third day. What i wanted to ask is, what can be the reason that he is not urinating as often, as he should or even stops doing it all at home? I didn't change anything in his living space for some time. Also i used to soak him up to 4 hours everyday in a warm water. I know, that soaking can't do no harm, but maybe 4 hours - it's too long and because of that he stopped urinating often? I was soaking him for so long, because he gets his eyes sunken even if humidity is about 35-40 in terrarium. Especially now, in winter. In summer i take him outside. I don't use substrate, because he tried to eat it. So i use underpads. Maybe someone has ideas, why my tortoise started to have such urinating problems at home?
