Signs of blood

[Scooby4]

My best friend's cat sleeps in the bathroom at night in their house. For the last few weeks they have noticed splotches of blood around where the cat may have laid at. Not alot of blood but very small spots. Not enough to indicate a wound or emergency conditions.
The cat was declawed last month. It had 6 toes so the declawing was more "difficult" than usual. The vet made note of this to pay "special" attention while it heals. The cat has also been fixed over 3 months ago. So far that is the ONLY surgery the cat has had.
The blood started showing up AFTER the declawing and stitches removed. However, there are NO bloody paw prints or even indications of any blood paws. The vet checked it out and the surgery has healed nicely. There is no sign of blood coming from this area.
The vet did notice the cat had fleas. It is an indoor cat and hasn't been exposed to many fleas. It could have gotten them in the waiting room of the vet's office for all that is known so far. The vet treated the cat for fleas and assigned "Flea dirt" as the cause for the mysterious blood stains.
My question is: Has anyone else had this happen to their cat? My cat has a notorious ear pimple issue that sometimes leads to finding spots of blood in the sink where she may sleep. My friend's cat has no pimples.
My opinion is that the blood seen is the "flea dirt". The cat has been treated with antibiotics and Advantix for now. Has anyone else had a similar issue and it NOT be "flea dirt"? I just would feel better to let my friend know what else to keep an eye on in case this isn't the real cause. Thanks.

I have never had this problem, the only time I did, was when my RB cat Twinkles had fleas. She would lay in the bathtub and when she jumped out, I thought she was bleeding. It was just from the flea dirt getting wet. I hope that is all it is, but it's best to keep an eye on him/her to make sure.

When my cat Mollie Rose was a kitten, she almost died from being infested with fleas, caused by my roommates dog. Mollie Rose is strictly indoors. The vet tech told me that her bath water was dark brown.

As long as your friend's cat is eating and using the litterbox, I wouldn't worry about it.

Thank you for the replies. I thought it was flea dirt too. My friend never heard of it before. I had to explain to her husband that it was simply "flea eggs" that have fed off the skin/blood of the cat. I've had to deal with this with my animals before.
I just wanted to make sure since all the test aren't back yet. Thanks!
