What is going on??

[aTailOf2Kitties]

the tail-chasing kinda concerns me. Makes me think either his anal sacs are uncomfortable or he has fleas hiding in that area. Is he fidgety while using the litterbox? Is he on flea prevention? Other than that I'm stumped unless it is just plain old stress or anxiety over something. Back when I worked at the vet years ago there was a little min-pin dog that would attack his tail. He tore himself up to the point he needed stitches and an e-collar more than once. They ended up putting him on some sort of anti-anxiety meds and it really helped

Boomer does not seem to have any troubles with going to the litterbox and he is not on flea prevention but they are strictly indoor cats. I will go over him and check for any flea dirt later tonight just in case.

My husband had a year long tour in central america to do before we could go over to Germany. Thankfully that is close to over!! He will come home in Feb to help us pack and then they will move us over there. I know very little German. I know what you said but I wouldn't be able to carry on a conversation.

Sounds like stress related biting. My Honeybun would do that to his paw and pull out chunks of fur. Since my one foster has gotten adopted, he's been much better and no more biting and pulling out fur, but had he not, I would have gotten him on an anti anxiety medication. Maybe the stuff Medusa (Mary) uses, Clomicalm, would work for him?

Have you used a water spray bottle to interrupt their battles at all? Maybe if the one stops the fighting, the other will stop attacking his own tail. Just thought.

those plug-ins for cat stress related behavior work great here.
they sell them everywhere but can be pricey.
