That’s odd!  My guess is he’s stressed and is showing his stress.  I saw your other post about the kittens…is HE neutered?  Do you have 4 litterboxes (one per cat plus one)?  Are those litterboxes VERY clean?

Bringing in new animals cause upheaval in a home, even if you do it the right way with slow introductions.  ASSUMING HE IS IN GOOD HEALTH, and assuming you’ve had him checked since this started, I’d suggest picking up some feliway from petsmart or petco.  I’d also prevent him from going into the bathroom with you.

Like I said: try Feliway. I’d also give him some personal time with you (away from the bathroom) – this COULD be his way of claiming you.

In case of Puking Foam , Her digestive system isn’t good. But blood is coming?!?? She got a stomach cancer. Keep calm and visit a vet as soon as possible if you want to save her.

I agree, I’d get him in today.

What could it be ?

For how long has this gone on?

This could be medical.  Have you taken your cat in to check for a UTI?  If not, this should be step 1.  Take a fresh urine sample with you, if possible.

This could also be behavioral.  Is your cat stressed?  Do you have two or more litterboxes (one per cat plus one), and does your cat use any of them?  Have you tried different litter types?  Has your schedule changed suddenly, or is someone new in your life?  Could your cat be bored?  Do you use room sprays and scents that might bother him?  Do you have other animals in your home, and could any of them be picking on him?  How about people – do you live with any other people, and could they be harassing or otherwise mistreating him when you’re not around?

It could be mange.  Get her to the vet for a skin scrape to determine the cause.

There are two types of mange.

Bald patches are not normal.

Do you have a question?

I cannot recommend a dose of medication for your dog.  I would contact the prescribing vet to find out their recommendation.

I would recommend a thunder shirt to see if that helps instead of medication.

Looks exactly like my dogs back right now, and we have a bad case of the fleas. I am calling an exterminator tomorrow, I would recommend doing the same and getting her treated with Front line and a flea collar
