I'm really worried about Zeus. He appeared to be straining to pee a bit ago - and when he did pee - it came out almost like a little pile of toothpaste. I looked around his area and I can now see white spots where he's been peeing...so that tells me there has been some calcium buildup. As many may remember - I lost Tiny to something like this - his urine was even worse - it came out like caulk which was firmer than what Zeus has. Now - it can't be the water - because he is on bottled water. He gets veggies almost every day (usually spring mix and carrot) - and he has some Purina rabbit feed. He gets some hay - usually whatever I have - timothy or coastal or once in a while I'll have alfalfa...but not often. (Maybe twice a year?) I'm trying to decide whether to do a sub-q injection tonight (I can get the dose) - but he is NOT going to be happy at all. I'd appreciate any suggestions of things I can do at home. I'm going to call the vet in the morning but the odds are good that she may not be there as I remember she was going on vacation very soon. I do have Baytril here if they recommend it and could give that. I think the worst part of all this is the fears from having seen this before (only a worse case) and remembering how horrid it was. I don't want Zeus to pick up on my stress.
