Officially Concerned

Meowm is officially concerned, one of us is having a strong ammonia smell in our urine. She has no idea which one of us it is. We are all being our normal selves and we seem to be drinking plenty of water. Meowm first noticed it in one of our litterboxes and thought maybe it was that particular box, but now the smell is in another box. Meowm hasn't paid the v-e-t for my last visit yet, and now she is looking at possibly having to have all our urine tested....and she wonders why she is stressed. Purrs would be very appreciated. ***UPDATE** Meowm talked to the vet and she said that (if Meowm remembers correctly) bacterial infections are rare in cats. She said if there were troubles it would be a UTI and that the cat would be going outside the box. Well, no one has been going outside the box that Meowm has seen or smelled. Still she is going to check around at home to be safe and then watch us like a hawk this weekend to see if anyone is straining to pee. Another option is maybe the new apartment, with it being a top floor apartment and being warmer, is causing the aroma to be stronger. Or it might be the current litter we are using, although we have been using it for some time. Something else Meowm is thinking about doing, is, one at a time, switching out our plastic litterboxes for metal ones. This way the aromas don't get stuck in the actual box. The vet did say that Meowm could bring Junior in and she would check his temperature if Meowm wanted her too. Meowm picked Junior because his ears have been real warm and his nose has been dry. However, that has been going on for awhile too. It's all a conundrum.
