Why is my cat weeing blood?

[BigPigLittlePig]

Exactly that - he is happy in himself, but I noticed once last week, and again last night, that when he had weed in the litter tray, the wee was very dark and there were drips of blood on the litter. I've checked him over and can't see any injuries to account for the blood, so am assuming it's come from within...

Could be a few things. Cystitis is one of them. He needs to see a vet IMMEDIATELY

The most common reason is a water infection. He'll need antibiotics, or there is a risk that it will spread up to his kidneys, which causes more serious issues.

Would it be possible to get a sample of his urine?

I'd take him to a vets. It's not an emergency, but I wouldn't wait any longer than tomorrow morning. Chances are that they will start ABs and see if it clears up, as weeing blood can be a symptom of other illnesses too.

Seconding cystitis.

My male cat used to get it, poor soul.

And yes, take him to the vet as soon as possible.

Ah - I thought you said you'd noticed yesterday and today. You actually said last week. I'd get him seen ASAP - He'll have had the infection a while now, if that's what it is, and it could cause serious harm.

caja I wouldn't even know how to go about getting a sample!

Will book an appointment for him. Thankyou

My elderly boy had this last week. He's nearly finished his antibiotics and had an anti-inflammatory for a few days, and seems a lot happier.

Get him seen asap - he's probably in a lot of pain.

If the vets need a sample they can draw it straight from his bladder with a syringe. Or they can give you special non absorbant crystals which you put into a (very clean/new) litter tray. You can then pour the urine into a little bottle they give you using a funnel which also comes in the pack. But if they suspect cystitis they will almost certainly give him an antibiotic injection immediately anyway to be on the safe side as it can cause serious problems if left untreated.

Barnaby, aged 2 had the same problem. I only found out he had blood in his urine when he peed on a carrier bag I had left on the floor. I was able to scoop up a little wee in a urine sample bottle I had and he was down the vets the next day. He was given antibiotics and I had to get another sample using non-absorbant litter, a pipette and a bottle. Bless him, he wanted to go out and I said "not until you wee in the tray" and he did there and then. He was then diagnosed with struvite crystals in his urine and has to have 2 tablets of cystophan a day for life, eat wet food and drink more. I spent £20 on a water fountain which he totally ignores preferring to drink out of a bowl in the bath and another in the shower! Luckily he is insured as the tablets cost £67 for 120 days worth. Apart from the extra food cost Barnaby is fine for now. Hope your kitty is ok.

My female cat occasionally gets this but it only lasts for about a day, then she is fine - she tends to spray in the house when it happens.

I was given metacam for her once, so I put a drop or two of that in her water but tbh she doesn't drink in the house anyway.

She is 14 now - it happens about once a year.

Get him to a vet right away

How is your cat?
