My parents have a similar, ongoing problem with a long-haired cat. Mom brushes it several times a day, but the cat still throws up hairballs and food and gets blockages.
Maybe your cat is just one that can’t deal with the fur, especially if it’s washing the dog! Perhaps it’s nerves: our old Agnes had a compulsive licking problem when Anoreth was born. The vet gave her a sedative injection. Maybe your cat is reacting to the change of environment, and a shot to mellow it out for a month or so would help.
I used to have the same problem w/ my 3 cats, now down to 2 =(.
A few months ago, I switched their cat food to Before Grain because of a show I just happened to catch w/ Mark Marrone. It was a show on cats and their diet.
He said cats cannot digest grain, therefore, they either throw it up and you have a very messy liter box.
I used to come home to at least 2 piles of barf everyday as well very messy boxes. Since I have switched, I rarely have any barf, except for the occasional hairball, which is now just hair and bile.
merrickpetcare.com is their website. Check it out. They are here in the good ole USA, Texas to be exact and just read their 5 promises.
I have had excellent results switching to this brand. Noticed the barf almost instantly ceased.
Oh, and NOTHING they use in their pet food comes from China. An added plus!
Love your tagline!
