FIP in cats

Can you please tell me what you make of this blood work? The cat been sick for 2 months vomiting after eating and lost so much weight - now weighing 6.5lbs He was acting normal up until 1 week ago where he will now only eat a little wet food and no dry This week has been very sleepy. 1 Vet we saw said from his symptoms and this massive change in blood work she thinks it’s liver/intestinal cancer.

Hello!   I'm afraid that this is blurred on my screen and, even after having opened this up on a computer screen rather than a phone, I am still unable to read the bloodwork - even the lines that you have circled.   I can see the bars but even with the numbers, think that I still have insufficient context to make a better clinical decision than your vet - or even as good a clinical decision.  Your vet can see (and feel) the patient, the numbers and knows the full context and history.  Blood tests do not tell you the 'answers':  they just give another piece of a jigsaw puzzle.  If their judgement is in doubt, or you just want to make sure, vets are rarely offended to be asked for a second opinion.  Indeed, it's sometimes great for a vets' peace of mind to have a more experienced vet look over a complex case (we all want what is best for the patient).  Veterinary pathologists will often look over bloods for example, but this should be done with the full context, permissions and proper clinical history. A second reason for not commenting is that with blood-work, especially red and white blood cells, it would still be my preference to check some measurements (such as PCV / Total solids) by hand.  Part of understanding the context is knowing whether or not this is necessary for the machine that has been used here. Cancer itself rarely shows on blood-work:  there is not a blood-test for 'cancer.'  Good questions to ask your vey include:  'What do you think is the mostly likely diagnosis here?'   'How sure are you?'  'Why do these bloods make you think that it's that?' and  'Do you have enough information to be sure?' plus or minus, 'would it be alright if I asked you to find a second opinion for me?' I hope that this helps a little at least.  Please do let us know how you get on.
