I gave Theodore his fluids this morning like we have for months now. This morning though there was blood on the needle when I pulled it out. I haven't see this before and Google was little help. Should I be concerned??
No matter how careful you are, once in awhile, you hit a blood vessel. If it happens again within the next few days, give your vet a call. I don't think there is a concern, but I'm not a vet. I gave subQs to 4 different cats and once in awhile, I had a small amount of blood. If you have more than a spot or two, I'd definitely give the vet a call though.
I agree with FFakeGourmet
. If this was just traces of blood on the needle, or a drop or two, you should be just fine. It can happen. There are lots of little vessels there, and occasionally you are going to hit one. It should NOT be a regular thing, though.
