Kirsten ,

You asked for honest comments, so here goes.

The site looks wonderful the style, fonts and images are very professional and attractive.

I like most of the articles with the following exceptions.

Inside/outside cats true life expectancy is between 16 to 18 years, NOT The low figure of five years you quoted. The low figures stupidly include early deaths of strays, ferals and kittens let out too early, ie Well loved cats live much longer.
It is totally misleading to lump these unloved and unsupervised cats deaths in with well cared for inside/outside cats.

Other big dangers to inside only cats are house fires, they can't escape and die due to inhaling smoke, playing in washing machines and tumble driers which are switched on with horrible results, being posioned by eating house plants if not provided with proper house grass needed to purge hairballs (outside cats just eat grass), no road sense so if they do get outside they have a higher chance of being run over or getting lost.

Outside cats do NOT run away unless you are abusive to them or ignore their needs. Some cats may return to an old address but this habit can easily be trained out of them.

Inside only males and females also need altering due to the health benefits of extended life and lower cancer risk, you only mention outside cats in this article.

I have been writing and writing and I am still not happy with any of my articles well I will keep trying.

I am amazed that you have had the time to put together this website in such a short time and in two languages no less.
