Nemo (our cat) had a Lower urinary tract inflammation a few weeks back and now

[sparklymieow]

He is so grumpy, he isn't eating, smells terrible, and isn't cleaning himself, his fur looks matty, should I take him back to the vet?

yes you should give them a call.
How old is he?

he is 2 years old, he was given lots of antib. but he doesn't seem himself, he attacked DH the other day, which isn'tvery unlike him

is very unlike him

You should definately take him back then as at 2 years old he should be bouncing back quicker than this.
Bless, probably needs different type of antibiotic.

we thought he was just being moody because I took him to the vet but he keeps peeing over the house, so everywhere smells [ewww] He also smells strong, which I have never noticed before, right going to phone the vet AGAIN!!
