Bless you for taking Puma in!He is jealous of the other cat hence he is marking

He was an outside cat in Mexico so he is used to standing up to other cats and defending his territory.

We can take some steps at home but if they don't work a vet can prescribe amitriptyline.

Go out and get melatonin pills and either turkey baby food or canned cat food turkey.Add 3 mg of melatonin to a tablespoon of food. Turkey contains l-triptophan so the combination will calm him

Give him 4 drops of cranberry juice by dropper every day for 7 days to lower the PH of his urine.

To stop him from bullying the other cat use a throw pillow to gently push him back if he approaches aggressively.

You MUST be consistent and do it EVERY single time! That way he knows his behavior will NOT be tolerated. BUT any time e approaches nicely he gets an immediate food treat so he sees GOOD behavior is instantly rewarded.

Please let me know how he is doing .
