Vaccinating against chlamydia. Is it worth it?

[Toddlerteaplease]

My two princesses are due their boosters. One of the vets they are registered with does chlamydia included in the course. Total cost £50 per cat. The other vets doesn't include it and doesn't vaccinate against it. Cost £23 per cat. Does anyone get them vaccinated for it. Can't decide which vets to take them too.

I get mine done for everything Toddler, but your girls don't go outside, do they? (mine indoor/outdoor) So possibly not necessary?

The cheaper vet doesn't even stock it. So they clearly feel there is no need for it. The more expensive vet is the one that saved Snorg's life and they are a bit more thorough but not sure I can justify the price difference just because of that!
