Can I give these to my cat?


I'm having this issue but it's with my cats. Would it be safe to give my cat one of these each day and if not, are there any cat-safe products that do the same?

  • Customer Service/Meds Advisor


Thank you for your query,

This product is absolutely fine to give to cats, similarly to dogs the dose is determined by the weight of the animal you wish to treat.

For cats between 1kg-5kg it is advised that you give one quarter of a tablet daily and for cats between 5kg-10kg you should give half a tablet daily.

I hope this helps you,

Mr Forsyth

How safe are green-um tablets in the long term

  • Non-Executive Director

This is a sensible question and as with many things in life, it is impossible to give 100% assurance of complete safety. However most of the ingredients are present (perhaps in lower levels) in many dog foods and these are very unlikely to cause any bad effects. They are widely taken by humans too. The only unusual ingredient quoted is Yucca Schidigera extract, which is a plant product not found in most dog foods or supplements. It is regarded as very safe and is present in some human preparations too.

I would regard this as a very safe supplement and safe to use long-term, but if possible do not give it through all the year. (When there is heavy rain, especially when plants are not growing rapidly due to cold weather, the browning effect on lawns is less apparent. If the urine is diluted and washed away by rain, it will not cause trouble anyway and then can act as a fertilizer in fact.)
