So I've got two female cats, a 1 year old and a 6 year old, and the younger one has such an ammonia stench to her pee that it's utterly noxious.
Common suggestions online are that the cat is dehydrated - which with two water fountains, wet food twice a day, and the sheer monsterous size of the pee clumps, is not the case. They've got three litter boxes which are scooped daily, so it's also not like we're leaving things to fester and grow more pungent. It's not a new development, her pee has always been really potent, so I'm also not thinking UTI.
I've tried sprinkling baking soda in the litter after scooping, which helps a bit with residual smells, but I'm looking for any suggestions to counter this constant ammonia assault.
The culprit:
Get her to a vet asap!
It could be a early indication of kidney problems.
My previous cat Tweet had similar issues and it was from his kidneys shutting down.
Unfortunately it wasn't caught early enough so even with medication and a low protein diet he passed over the rainbow bridge a month later.
