My male RES is 14 this year. And these days he has been pooping kind of irregularly. There were no changes to his diet. But today is the third day of his constipation and I tried not to feed him his regular Mazuri pellets and gave him some cucumber(I thought it might provide more moisture to his stools) , banana, lettuce and his usual kale instead. I also massaged his rear area a bit hoping it would help (now I really regret dong so...
After that he wouldn't stop blinking his eyes, sometimes he'd close them for a long while. He's still rather active. But now it's near bedtime he's been closing his eyes unless I talk to him/get his attention. Could I have hurt any of his glands while massaging him?
I know this is very bad but we don't have a proper habitat for my RES yet. I've been trying to build one but the space constraint in my apartment makes it difficult. We sun them when the sun shines into the apartment. And I live in a tropical country where the temperature is always above 25 degrees celsius. I recently tried to bask my RES under an exoterra bulb we bought, could it be a contributing factor to his eye problem? But the last time he was under that bulb was two days ago and he only started the weird blinking a couple hours ago.
I've called the vet to book for an appointment tomorrow morning but I'm so worried. Please help out if you know why, thank you very much~
