Took boy cat to vet Saturday night as I noticed he was going to the litter tray repeatedly and only doing tiny little wees. Vet prescribed metacam and cystaid, said he wasn't blocked, bladder was nearly empty. He is able to go for a wee and sizes range from a teaspoon to a couple of dessert spoons I'd say. I'm used to seeing much bigger wees from him though. He is going to the litter box very frequently, sometimes in quick succession with not much to show for it.
I'm starting to doubt myself now though. He's always been a bit of a funny bugger in that as soon as I'd empty a litter tray he'd rush in and go again (I must empty the litter trays at least 4 times a day, this isn't me letting them get dirty!) My question is, could he just be 'marking' (with wee) a clean litter tray, rather than having cystitis? He's very perky in himself now (whereas on Saturday he hid under the bed all day, adding to my cystitis suspicions). I'm worried I'll finish the metacam and he'll still be doing his micro wees and I'll be none the wiser. I don't want him having anything invasive. I'm planning on getting a wee sample to the vet on Wednesday morning (when I'm home).
