One of my cats is suffering from a nasty bought of dry skin. He's a new adoptee, and is quite overweight. I am feeding him a healthy amount of wet food, and although he has access to free feeding of dry, does not seem to participate in the munching of the crunches.
I noticed the dry skin fairly soon after adopting him, but have tried to give him time to adjust to his new diet. The problem hasn't resolved itself yet, so my next step is to try some salmon oil or fish oil. I have consulted a vet on this.
Only, the oils marketed to pet owners are incredibly overpriced compared to the capsules marketed to humans. I want to buy the cheaper option, because it irks me that the cat version is $10 or more simply because it has "for cats" on the label.
Are they truly equal? If I buy the human salmon oil, can I just pop it open onto his wet food and be done with it, or is there ingredients (or lack of ingredients) that make the cat salmon oil special?
